Data Sheet
Notice On Data Sheet Designations
Spansion Inc. issues data sheets with Advance Information or Preliminary designations to advise readers of
product information or intended specifications throughout the product life cycle, including development,
qualification, initial production, and full production. In all cases, however, readers are encouraged to verify
that they have the latest information before finalizing their design. The following descriptions of Spansion data
sheet designations are presented here to highlight their presence and definitions.
Advance Information
The Advance Information designation indicates that Spansion Inc. is developing one or more specific
products, but has not committed any design to production. Information presented in a document with this
designation is likely to change, and in some cases, development on the product may discontinue. Spansion
Inc. therefore places the following conditions upon Advance Information content:
“This document contains information on one or more products under development at Spansion Inc.
The information is intended to help you evaluate this product. Do not design in this product without
contacting the factory. Spansion Inc. reserves the right to change or discontinue work on this proposed
product without notice.”
Preliminary
The Preliminary designation indicates that the product development has progressed such that a commitment
to production has taken place. This designation covers several aspects of the product life cycle, including
product qualification, initial production, and the subsequent phases in the manufacturing process that occur
before full production is achieved. Changes to the technical specifications presented in a Preliminary
document should be expected while keeping these aspects of production under consideration. Spansion
places the following conditions upon Preliminary content:
“This document states the current technical specifications regarding the Spansion product(s)
described herein. The Preliminary status of this document indicates that product qualification has been
completed, and that initial production has begun. Due to the phases of the manufacturing process that
require maintaining efficiency and quality, this document may be revised by subsequent versions or
modifications due to changes in technical specifications.”
Combination
Some data sheets contain a combination of products with different designations (Advance Information,
Preliminary, or Full Production). This type of document distinguishes these products and their designations
wherever necessary, typically on the first page, the ordering information page, and pages with the DC
Characteristics table and the AC Erase and Program table (in the table notes). The disclaimer on the first
page refers the reader to the notice on this page.
Full Production (No Designation on Document)
When a product has been in production for a period of time such that no changes or only nominal changes
are expected, the Preliminary designation is removed from the data sheet. Nominal changes may include
those affecting the number of ordering part numbers available, such as the addition or deletion of a speed
option, temperature range, package type, or VIO range. Changes may also include those needed to clarify a
description or to correct a typographical error or incorrect specification. Spansion Inc. applies the following
conditions to documents in this category:
“This document states the current technical specifications regarding the Spansion product(s)
described herein. Spansion Inc. deems the products to have been in sufficient production volume such
that subsequent versions of this document are not expected to change. However, typographical or
specification corrections, or modifications to the valid combinations offered may occur.”
Questions regarding these document designations may be directed to your local sales office.

1. Product Overview
The GL-S family consists of 128-Mbit to 1Gbit, 3.0V core, Versatile I/O, non-volatile, flash memory devices.
These devices have a 16-bit (word) wide data bus and use only word boundary addresses. All read accesses
provide 16 bits of data on each bus transfer cycle. All writes take 16 bits of data from each bus transfer cycle.
Figure 1.1 Block Diagram
:
Note:
** AMAX GL01GS = A25, AMAX GL512S = A24, AMAX GL256S = A23, AMAX GL128S = A22
The GL-S family combines the best features of eXecute In Place (XIP) and Data Storage flash memories.
This family has the fast random access of XIP flash along with the high density and fast program speed of
Data Storage flash.
Read access to any random location takes 90 ns to 120 ns depending on device density and I/O power
supply voltage. Each random (initial) access reads an entire 32-byte aligned group of data called a Page.
Other words within the same Page may be read by changing only the low order 4 bits of word address. Each
access within the same Page takes 15 ns to 30 ns. This is called Page Mode read. Changing any of the
higher word address bits will select a different Page and begin a new initial access. All read accesses are
asynchronous.

Data Sheet
The device control logic is subdivided into two parallel operating sections, the Host Interface Controller (HIC)
and the Embedded Algorithm Controller (EAC). HIC monitors signal levels on the device inputs and drives
outputs as needed to complete read and write data transfers with the host system. HIC delivers data from the
currently entered address map on read transfers; places write transfer address and data information into the
EAC command memory; notifies the EAC of power transition, hardware reset, and write transfers. The EAC
looks in the command memory, after a write transfer, for legal command sequences and performs the related
Embedded Algorithms.
Changing the non-volatile data in the memory array requires a complex sequence of operations that are
called Embedded Algorithms (EA). The algorithms are managed entirely by the device internal EAC. The
main algorithms perform programming and erase of the main array data. The host system writes command
codes to the flash device address space. The EAC receives the commands, performs all the necessary steps
to complete the command, and provides status information during the progress of an EA.
The erased state of each memory bit is a logic 1. Programming changes a logic 1 (High) to a logic 0 (Low).
Only an Erase operation is able to change a 0 to a 1. An erase operation must be performed on an entire
128-kbyte aligned and length group of data call a Sector. When shipped from Spansion all Sectors are
erased.
Programming is done via a 512-byte Write Buffer. It is possible to write from 1 to 256 words, anywhere within
the Write Buffer before starting a programming operation. Within the flash memory array, each 512-byte
aligned group of 512 bytes is called a Line. A programming operation transfers volatile data from the Write
Buffer to a non-volatile memory array Line. The operation is called Write Buffer Programming.
The Write Buffer is filled with 1’s after reset or the completion of any operation using the Write Buffer. Any
locations not written to a 0 by a Write to Buffer command are by default still filled with 1’s. Any 1’s in the Write
Buffer do not affect data in the memory array during a programming operation.
As each Page of data that was loaded into the Write Buffer is transferred to a memory array Line.
Sectors may be individually protected from program and erase operations by the Advanced Sector Protection
(ASP) feature set. ASP provides several, hardware and software controlled, volatile and non-volatile,
methods to select which sectors are protected from program and erase operations.

2. Address Space Maps
There are several separate address spaces that may appear within the address range of the flash memory
device. One address space is visible (entered) at any given time.
Flash Memory Array: the main non-volatile memory array used for storage of data that may be randomly
accessed by asynchronous read operations.
ID/CFI: a memory array used for Spansion factory programmed device characteristics information. This
area contains the Device Identification (ID) and Common Flash Interface (CFI) information tables.
Secure Silicon Region (SSR): a One Time Programmable (OTP) non-volatile memory array used for
Spansion factory programmed permanent data, and customer programmable permanent data.
Lock Register: an OTP non-volatile word used to configure the ASP features and lock the SSR.
Persistent Protection Bits (PPB): a non-volatile flash memory array with one bit for each Sector. When
programmed, each bit protects the related Sector from erasure and programming.
PPB Lock: a volatile register bit used to enable or disable programming and erasure of the PPB bits.
Password: an OTP non-volatile array used to store a 64-bit password used to enable changing the state of
the PPB Lock Bit when using Password Mode sector protection.
Dynamic Protection Bits (DYB): a volatile array with one bit for each Sector. When set, each bit protects the
related Sector from erasure and programming.
Status Register: a volatile register used to display Embedded Algorithm status.
Data Polling Status: a volatile register used as an alternate, legacy software compatible, way to display
Embedded Algorithm status.
The main Flash Memory Array is the primary and default address space but, it may be overlaid by one other
address space, at any one time. Each alternate address space is called an Address Space Overlay (ASO).
Each ASO replaces (overlays) the entire flash device address range. Any address range not defined by a
particular ASO address map, is reserved for future use. All read accesses outside of an ASO address map
returns non-valid (undefined) data. The locations will display actively driven data but the meaning of whatever
1’s or 0’s appear are not defined.
There are four device operating modes that determine what appears in the flash device address space at any
given time:
Read Mode
Data Polling Mode
Status Register (SR) Mode
Address Space Overlay (ASO) Mode
In Read Mode the entire Flash Memory Array may be directly read by the host system memory controller. The
memory device Embedded Algorithm Controller (EAC), puts the device in Read mode during Power-on, after
a Hardware Reset, after a Command Reset, or after an Embedded Algorithm (EA) is suspended. Read
accesses and command writes are accepted in read mode. A subset of commands are accepted in read
mode when an EA is suspended.
While in any mode, the Status Register read command may be issued to cause the Status Register ASO to
appear at every word address in the device address space. In this Status Register ASO Mode, the device
interface waits for a read access and, any write access is ignored. The next read access to the device
accesses the content of the status register, exits the Status Register ASO, and returns to the previous
(calling) mode in which the Status Register read command was received.
In EA mode the EAC is performing an Embedded Algorithm, such as programming or erasing a non-volatile
memory array. While in EA mode, none of the main Flash Memory Array is readable because the entire flash
device address space is replaced by the Data Polling Status ASO. Data Polling Status will appear at every
word location in the device address space.

Data Sheet
While in EA mode, only a Program / Erase suspend command or the Status Register Read command will be
accepted. All other commands are ignored. Thus, no other ASO may be entered from the EA mode.
When an Embedded Algorithm is suspended, the Data Polling ASO is visible until the device has suspended
the EA. When the EA is suspended the Data Polling ASO is exited and Flash Array data is available. The
Data Polling ASO is reentered when the suspended EA is resumed, until the EA is again suspended or
finished. When an Embedded Algorithm is completed, the Data Polling ASO is exited and the device goes to
the previous (calling) mode (from which the Embedded Algorithm was started).
In ASO mode, one of the remaining overlay address spaces is entered (overlaid on the main Flash Array
address map). Only one ASO may be entered at any one time. Commands to the device affect the currently
entered ASO. Only certain commands are valid for each ASO. These are listed in the Table 6.1 on page 57,
in each ASO related section of the table.
The following ASOs have non-volatile data that may be programmed to change 1’s to 0’s:
Secure Silicon Region
Lock Register
Persistent Protection Bits (PPB)
Password
Only the PPB ASO has non-volatile data that may be erased to change 0’s to 1’s
When a program or erase command is issued while one of the non-volatile ASOs is entered, the EA operates
on the ASO. The ASO is not readable while the EA is active. When the EA is completed the ASO remains
entered and is again readable. Suspend and Resume commands are ignored during an EA operating on any
of these ASOs.

Data Sheet
Note: These tables have been condensed to show sector related information for an entire device on a single
page Sectors and their address ranges that are not explicitly listed (such as SA001-SA510) have sectors
starting and ending addresses that form the same pattern as all other sectors of that size. For example, all
128 kB sectors have the pattern XXX0000h-XXXFFFFh.
2.2 Device ID and CFI (ID-CFI) ASO
There are two traditional methods for systems to identify the type of flash memory installed in the system.
One has traditionally been called Autoselect and is now referred to as Device Identification (ID). The other
method is called Common Flash Interface (CFI).
For ID, a command is used to enable an address space overlay where up to 16 word locations can be read to
get JEDEC manufacturer identification (ID), device ID, and some configuration and protection status
information from the flash memory. The system can use the manufacturer and device IDs to select the
appropriate driver software to use with the flash device.
CFI also uses a command to enable an address space overlay where an extendable table of standard
information about how the flash memory is organized and operates can be read. With this method the driver
software does not have to be written with the specifics of each possible memory device in mind. Instead the
driver software is written in a more general way to handle many different devices but adjusts the driver
behavior based on the information in the CFI table.
Traditionally these two address spaces have used separate commands and were separate overlays.
However, the mapping of these two address spaces are non-overlapping and so can be combined in to a
single address space and appear together in a single overlay. Either of the traditional commands used to
access (enter) the Autoselect (ID) or CFI overlay will cause the now combined ID-CFI address map to appear.
The ID-CFI address map appears within, and overlays the Flash Array data of, the sector selected by the
address used in the ID-CFI enter command. While the ID-CFI ASO is entered the content of all other sectors
is undefined.
The ID-CFI address map starts at location 0 of the selected sector. Locations above the maximum defined
address of the ID-CFI ASO to the maximum address of the selected sector have undefined data. The ID-CFI
enter commands use the same address and data values used on previous generation memories to access
the JEDEC Manufacturer ID (Autoselect) and Common Flash Interface (CFI) information, respectively.
For the complete address map see Table 6.2 on page 60.

Data Sheet
2.2.1 Device ID
The Joint Electron Device Engineering Council (JEDEC) standard JEP106T defines the manufacturer ID for a
compliant memory. Common industry usage defined a method and format for reading the manufacturer ID
and a device specific ID from a memory device. The manufacturer and device ID information is primarily
intended for programming equipment to automatically match a device with the corresponding programming
algorithm. Spansion has added additional fields within this 32-byte address space.
The original industry format was structured to work with any memory data bus width e. g. x8, x16, x32. The ID
code values are traditionally byte wide but are located at bus width address boundaries such that
incrementing the device address inputs will read successive byte, word, or double word locations with the ID
codes always located in the least significant byte location of the data bus. Because the device data bus is
word wide each code byte is located in the lower half of each word location. The original industry format made
the high order byte always 0. Spansion has modified the format to use both bytes in some words of the
address space. For the detail description of the Device ID address map see Table 6.2 on page 60.
2.2.2 Common Flash Memory Interface
The JEDEC Common Flash Interface (CFI) specification (JESD68.01) defines a standardized data structure
that may be read from a flash memory device, which allows vendor-specified software algorithms to be used
for entire families of devices. The data structure contains information for system configuration such as various
electrical and timing parameters, and special functions supported by the device. Software support can then
be device-independent, Device ID-independent, and forward-and-backward-compatible for entire Flash
device families.
The system can read CFI information at the addresses within the selected sector as shown in Device ID and
Common Flash Interface (ID-CFI) ASO Map on page 60.
Like the Device ID information, CFI information is structured to work with any memory data bus width e. g. x8,
x16, x32. The code values are always byte wide but are located at data bus width address boundaries such
that incrementing the device address reads successive byte, word, or double word locations with the codes
always located in the least significant byte location of the data bus. Because the data bus is word wide each
code byte is located in the lower half of each word location and the high order byte is always 0.
For further information, please refer to the Spansion CFI Specification, Version 1.4 (or later), and the JEDEC
publications JEP137-A and JESD68.01. Please contact JEDEC (http://www.jedec.org/) for their standards
and the Spansion CFI Specification may be found at the Spansion Web site
(http://www.spansion.com/Support/TechnicalDocuments/Pages/ApplicationNotes.aspx at the time of this
document's publication) or by contacting a local Spansion sales office listed on the web site.
2.3 Status Register ASO
The Status Register ASO contains a single word of registered volatile status for Embedded Algorithms. When
the Status Register read command is issued, the current status is captured (by the rising edge of WE#) into
the register and the ASO is entered. The Status Register content appears on all word locations. The first read
access exits the Status Register ASO (with the rising edge of CE# or OE#) and returns to the address space
map in use when the Status Register read command was issued. Write commands will not exit the Status
Register ASO state.

Data Sheet
2.4 Data Polling Status ASO
The Data Polling Status ASO contains a single word of volatile memory indicating the progress of an EA. The
Data Polling Status ASO is entered immediately following the last write cycle of any command sequence that
initiates an EA. Commands that initiate an EA are:
Word Program
Program Buffer to Flash
Chip Erase
Sector Erase
Erase Resume / Program Resume
Program Resume Enhanced Method
Blank Check
Lock Register Program
Password Program
PPB Program
All PPB Erase
The Data Polling Status word appears at all word locations in the device address space. When an EA is
completed the Data Polling Status ASO is exited and the device address space returns to the address map
mode where the EA was started.
2.5 Secure Silicon Region ASO
The Secure Silicon Region (SSR) provides an extra flash memory area that can be programmed once and
permanently protected from further changes i. e. it is a One Time Program (OTP) area. The SSR is
1024 bytes in length. It consists of 512 bytes for Factory Locked Secure Silicon Region and 512 bytes for
Customer Locked Secure Silicon Region.
The sector address supplied during the Secure Silicon Entry command selects the Flash Memory Array
sector that is overlaid by the Secure Silicon Region address map. The SSR is overlaid starting at location 0 in
the selected sector. Use of the sector 0 address is recommended for future compatibility. While the SSR ASO
is entered the content of all other sectors is undefined. Locations above the maximum defined address of the
SSR ASO to the maximum address of the selected sector have undefined data.

2.6 Sector Protection Control
2.6.1 Lock Register ASO
The Lock register ASO contains a single word of OTP memory. When the ASO is entered the Lock Register
appears at all word locations in the device address space. However, it is recommended to read or program
the Lock Register only at location 0 of the device address space for future compatibility.
2.6.2 Persistent Protection Bits (PPB) ASO
The PPB ASO contains one bit of a Flash Memory Array for each Sector in the device. When the PPB ASO is
entered, the PPB bit for a sector appears in the Least Significant Bit (LSB) of each address in the sector.
Reading any address in a sector displays data where the LSB indicates the non-volatile protection status for
that sector. However, it is recommended to read or program the PPB only at address 0 of the sector for future
compatibility. If the bit is 0 the sector is protected against programming and erase operations. If the bit is 1 the
sector is not protected by the PPB. The sector may be protected by other features of ASP.
2.6.3 PPB LOCK ASO
The PPB Lock ASO contains a single bit of volatile memory. The bit controls whether the bits in the PPB ASO
may be programmed or erased. If the bit is 0 the PPB ASO is protected against programming and erase
operations. If the bit is 1 the PPB ASO is not protected. When the PPB Lock ASO is entered the PPB Lock bit
appears in the Least Significant Bit (LSB) of each address in the device address space. However, it is
recommended to read or program the PPB Lock only at address 0 of the device for future compatibility.
2.6.4 Password ASO
The Password ASO contains four words of OTP memory. When the ASO is entered the Password appears
starting at address 0 in the device address space. All locations above the forth word are undefined.
2.6.5 Dynamic Protection Bits (DYB) ASO
The DYB ASO contains one bit of a volatile memory array for each Sector in the device. When the DYB ASO
is entered, the DYB bit for a sector appears in the Least Significant Bit (LSB) of each address in the sector.
Reading any address in a sector displays data where the LSB indicates the non-volatile protection status for
that sector. However, it is recommended to read, set, or clear the DYB only at address 0 of the sector for
future compatibility. If the bit is 0 the sector is protected against programming and erase operations. If the bit
is 1 the sector is not protected by the DYB. The sector may be protected by other features of ASP.

3. Data Protection
The device offers several features to prevent malicious or accidental modification of any sector via hardware
means.
3.1 Device Protection Methods
3.1.1 Power-Up Write Inhibit
RESET#, CE#, WE#, and, OE# are ignored during Power-On Reset (POR). During POR, the device can not
be selected, will not accept commands on the rising edge of WE#, and does not drive outputs. The Host
Interface Controller (HIC) and Embedded Algorithm Controller (EAC) are reset to their standby states, ready
for reading array data, during POR. CE# or OE# must go to VIH before the end of POR (tVCS).
At the end of POR the device conditions are:
all internal configuration information is loaded,
the device is in read mode,
the Status Register is at default value,
all bits in the DYB ASO are set to un-protect all sectors,
the Write Buffer is loaded with all 1’s,
the EAC is in the standby state.
3.1.2 Low VCC Write Inhibit
When VCC is less than VLKO, the HIC does not accept any write cycles and the EAC resets. This protects data
during VCC power-up and power-down. The system must provide the proper signals to the control pins to
prevent unintentional writes when VCC is greater than VLKO.
3.2 Command Protection
Embedded Algorithms are initiated by writing command sequences into the EAC command memory. The
command memory array is not readable by the host system and has no ASO. Each host interface write is a
command or part of a command sequence to the device. The EAC examines the address and data in each
write transfer to determine if the write is part of a legal command sequence. When a legal command
sequence is complete the EAC will initiate the appropriate EA.
Writing incorrect address or data values, or writing them in an improper sequence, will generally result in the
EAC returning to its Standby state. However, such an improper command sequence may place the device in
an unknown state, in which case the system must write the reset command, or possibly provide a hardware
reset by driving the RESET# signal Low, to return the EAC to its Standby state, ready for random read.
The address provided in each write may contain a bit pattern used to help identify the write as a command to
the device. The upper portion of the address may also select the sector address on which the command
operation is to be performed. The Sector Address (SA) includes AMAX through A16 flash address bits (system
byte address signals amax through a17). A command bit pattern is located in A10 to A0 flash address bits
(system byte address signals a11 through a1).
The data in each write may be: a bit pattern used to help identify the write as a command, a code that
identifies the command operation to be performed, or supply information needed to perform the operation.
See Table 6.1 on page 57 for a listing of all commands accepted by the device.
3.3 Secure Silicon Region (OTP)
The Secure Silicon Region (SSR) provides an extra flash memory area that can be programmed once and
permanently protected from further changes i. e. it is a One Time Program (OTP) area. The SSR is
1024 bytes in length. It consists of 512 bytes for Factory Locked Secure Silicon Region and 512 bytes for
Customer Locked Secure Silicon Region.

3.4 Sector Protection Methods
3.4.1 Write Protect Signal
If WP# = VIL, the lowest or highest address sector is protected from program or erase operations independent
of any other ASP configuration. Whether it is the lowest or highest sector depends on the device ordering
option (model) selected. If WP# = VIH, the lowest or highest address sector is not protected by the WP# signal
but it may be protected by other aspects of ASP configuration. WP# has an internal pull-up; when
unconnected, WP# is at VIH.
3.4.2 ASP
Advanced Sector Protection (ASP) is a set of independent hardware and software methods used to disable or
enable programming or erase operations, individually, in any or all sectors. This section describes the various
methods of protecting data stored in the memory array. An overview of these methods is shown in Figure 3.1.
Figure 3.1 Advanced Sector Protection Overview
Every main flash array sector has a non-volatile (PPB) and a volatile (DYB) protection bit associated with it.
When either bit is 0, the sector is protected from program and erase operations.
The PPB bits are protected from program and erase when the PPB Lock bit is 0. There are two methods for
managing the state of the PPB Lock bit, Persistent Protection and Password Protection.
The Persistent Protection method sets the PPB Lock to 1 during POR or Hardware Reset so that the PPB bits
are unprotected by a device reset. There is a command to clear the PPB Lock bit to 0 to protect the PPB bits.

Data Sheet
There is no command in the Persistent Protection method to set the PPB Lock bit therefore the PPB Lock bit
will remain at 0 until the next power-off or hardware reset. The Persistent Protection method allows boot code
the option of changing sector protection by programming or erasing the PPB, then protecting the PPB from
further change for the remainder of normal system operation by clearing the PPB Lock bit. This is sometimes
called Boot-code controlled sector protection.
The Password method clears the PPB Lock bit to 0 during POR or Hardware Reset to protect the PPB. A 64-
bit password may be permanently programmed and hidden for the password method. A command can be
used to provide a password for comparison with the hidden password. If the password matches the PPB Lock
bit is set to 1 to unprotect the PPB. A command can be used to clear the PPB Lock bit to 0.
The selection of the PPB Lock management method is made by programming OTP bits in the Lock Register
so as to permanently select the method used.
The Lock Register also contains OTP bits, for protecting the SSR.
The PPB bits are erased so that all main flash array sectors are unprotected when shipped from Spansion.
The Secured Silicon Region can be factory protected or left unprotected depending on the ordering option
(model) ordered.
3.4.3 PPB Lock
The Persistent Protection Bit Lock is a volatile bit for protecting all PPB bits. When cleared to 0, it locks all
PPBs and when set to 1, it allows the PPBs to be changed. There is only one PPB Lock Bit per device.
The PPB Lock command is used to clear the bit to 0. The PPB Lock Bit must be cleared to 0 only after all the
PPBs are configured to the desired settings.
In Persistent Protection mode, the PPB Lock is set to 1 during POR or a hardware reset. When cleared, no
software command sequence can set the PPB Lock, only another hardware reset or power-up can set the
PPB Lock bit.
In the Password Protection mode, the PPB Lock is cleared to 0 during POR or a hardware reset. The PPB
Lock can only set to 1 by the Password Unlock command sequence. The PPB Lock can be cleared by the
PPB Lock Bit Clear command.
3.4.4 Persistent Protection Bits (PPB)
The Persistent Protection Bits (PPB) are located in a separate nonvolatile flash array. One of the PPB bits is
assigned to each sector. When a PPB is 0 its related sector is protected from program and erase operations.
The PPB are programmed individually but must be erased as a group, similar to the way individual words may
be programmed in the main array but an entire sector must be erased at the same time. Preprogramming and
verification prior to erasure are handled by the EAC.
Programming a PPB bit requires the typical word programming time. During a PPB bit programming operation
or PPB bit erasing, Data polling Status DQ6 Toggle Bit I will toggle until the operation is complete. Erasing all
the PPBs requires typical sector erase time.
If the PPB Lock is 0, the PPB Program or erase commands do not execute and time-out without programming
or erasing the PPB.
The protection state of a PPB for a given sector can be verified by executing a PPB Status Read command
when entered in the PPB ASO.
3.4.5 Dynamic Protection Bits (DYB)
Dynamic Protection Bits are volatile and unique for each sector and can be individually modified. DYBs only
control protection for sectors that have their PPBs erased. By issuing the DYB Set or Clear command
sequences, the DYB are set to 0 or cleared to 1, thus placing each sector in the protected or unprotected
state respectively, if the PPB for the Sector is 1. This feature allows software to easily protect sectors against
inadvertent changes, yet does not prevent the easy removal of protection when changes are needed.
The DYB can be set to 0 or cleared to 1 as often as needed.

Data Sheet
3.4.6 Sector Protection States Summary
Each sector can be in one of the following protection states:
Unlocked – The sector is unprotected and protection can be changed by a simple command. The
protection state defaults to unprotected after a power cycle or hardware reset.
Dynamically Locked – A sector is protected and protection can be changed by a simple command. The
protection state is not saved across a power cycle or hardware reset.
Persistently Locked – A sector is protected and protection can only be changed if the PPB Lock Bit is set to
1. The protection state is non-volatile and saved across a power cycle or hardware reset. Changing the
protection state requires programming or erase of the PPB bits.
3.4.7 Lock Register
The Lock Register holds the non-volatile OTP bits for controlling protection of the SSR, and determining the
PPB Lock bit management method (protection mode).
The Secure Silicon Region (SSR) protection bits must be used with caution, as once locked, there is no
procedure available for unlocking the protected portion of the Secure Silicon Region and none of the bits in
the protected Secure Silicon Region memory space can be modified in any way. Once the Secure Silicon
Region area is protected, any further attempts to program in the area will fail with status indicating the area
being programmed is protected. The Region 0 Indicator Bit is located in the Lock Register at bit location 0 and
Region 1 in bit location 6.
As shipped from the factory, all devices default to the Persistent Protection method, with all sectors
unprotected, when power is applied. The device programmer or host system can then choose which sector
protection method to use. Programming either of the following two, one-time programmable, non-volatile bits,
locks the part permanently in that mode:
Persistent Protection Mode Lock Bit (DQ1)
Password Protection Mode Lock Bit (DQ2)

Data Sheet
If both lock bits are selected to be programmed at the same time, the operation will abort. Once the Password
Mode Lock Bit is programmed, the Persistent Mode Lock Bit is permanently disabled and no changes to the
protection scheme are allowed. Similarly, if the Persistent Mode Lock Bit is programmed, the Password Mode
is permanently disabled.
If the password mode is to be chosen, the password must be programmed prior to setting the corresponding
lock register bit. Setting the Password Protection Mode Lock Bit is programmed, a power cycle, hardware
reset, or PPB Lock Bit Set command is required to set the PPB Lock bit to 0 to protect the PPB array.
The programming time of the Lock Register is the same as the typical word programming time. During a Lock
Register programming EA, Data polling Status DQ6 Toggle Bit I will toggle until the programming has
completed. The system can also determine the status of the lock register programming by reading the Status
Register. See Status Register on page 37 for information on these status bits.
The user is not required to program DQ2 or DQ1, and DQ6 or DQ0 bits at the same time. This allows the user
to lock the SSR before or after choosing the device protection scheme. When programming the Lock Bits, the
Reserved Bits must be 1 (masked).
3.4.8 Persistent Protection Mode
The Persistent Protection method sets the PPB Lock to 1 during POR or Hardware Reset so that the PPB bits
are unprotected by a device reset. There is a command to clear the PPB Lock bit to 0 to protect the PPB.
There is no command in the Persistent Protection method to set the PPB Lock bit to 1 therefore the PPB Lock
bit will remain at 0 until the next power-off or hardware reset.
3.4.9 Password Protection Mode
3.4.9.1 PPB Password Protection Mode
PPB Password Protection Mode allows an even higher level of security than the Persistent Sector Protection
Mode, by requiring a 64-bit password for setting the PPB Lock. In addition to this password requirement, after
power up and reset, the PPB Lock is cleared to 0 to ensure protection at power-up. Successful execution of
the Password Unlock command by entering the entire password sets the PPB Lock to 1, allowing for sector
PPB modifications.
Password Protection Notes:
The Password Program Command is only capable of programming 0’s.
The password is all 1’s when shipped from Spansion. It is located in its own memory space and is
accessible through the use of the Password Program and Password Read commands.
All 64-bit password combinations are valid as a password.
Once the Password is programmed and verified, the Password Mode Locking Bit must be set in order to
prevent reading or modification of the password.
The Password Mode Lock Bit, once programmed, prevents reading the 64-bit password on the data bus
and further password programming. All further program and read commands to the password region are
disabled (data is read as 1's) and these commands are ignored. There is no means to verify what the
password is after the Password Protection Mode Lock Bit is programmed. Password verification is only
allowed before selecting the Password Protection mode.
The Password Mode Lock Bit is not erasable.
The exact password must be entered in order for the unlocking function to occur.
The addresses can be loaded in any order but all 4 words are required for a successful match to occur.
The Sector Addresses and Word Line Addresses are compared while the password address/data are
loaded. If the Sector Adddress don't match than the error will be reported at the end of that write cycle. The
status register will return to the ready state with the Program Status Bit set to 1, Program Status Register
Bit set to 1, and Write Buffer Abort Status Bit set to 1 indicating a failed programming operation. It is a
failure to change the state of the PPB Lock bit because it is still protected by the lack of a valid password.
The data polling status will remain active, with DQ7 set to the complement of the DQ7 bit in the last word of
the password unlock command, and DQ6 toggling. RY/BY# will remain low.
October 9, 2013 S29GL_128S_01GS_00_08 GL-S MirrorBit®Family 23
Data Sheet
The specific address and data are compared after the Program Buffer To Flash command has been given.
If they don't match to the internal set value than the status register will return to the ready state with the
Program Status Bit set to 1 and Program Status Register Bit set to 1 indicating a failed programming
operation. It is a failure to change the state of the PPB Lock bit because it is still protected by the lack of a
valid password. The data polling status will remain active, with DQ7 set to the complement of the DQ7 bit in
the last word of the password unlock command, and DQ6 toggling. RY/BY# will remain low.
The device requires approximately 100 µs for setting the PPB Lock after the valid 64-bit password is given
to the device.
The Password Unlock command cannot be accepted any faster than once every 100 µs ± 20 µs. This
makes it take an unreasonably long time (58 million years) for a hacker to run through all the 64-bit
combinations in an attempt to correctly match a password. The EA status checking methods may be used
to determine when the EAC is ready to accept a new password command.
If the password is lost after setting the Password Mode Lock Bit, there is no way to clear the PPB Lock.

4. Read Operations
4.1 Asynchronous Read
Each read access may be made to any location in the memory (random access). Each random access is self-
timed with the same latency from CE# or address to valid data (tACC or tCE).
4.2 Page Mode Read
Each random read accesses an entire 32-byte Page in parallel. Subsequent reads within the same Page
have faster read access speed. The Page is selected by the higher address bits (AMAX-A4), while the specific
word of that page is selected by the least significant address bits A3-A0. The higher address bits are kept
constant and only A3-A0 changed to select a different word in the same Page. This is an asynchronous
access with data appearing on DQ15-DQ0 when CE# remains Low, OE# remains Low, and the
asynchronous Page access time (tPAC C) is satisfied. If CE# goes High and returns Low for a subsequent
access, a random read access is performed and time is required (tACC or tCE).

5. Embedded Operations
5.1 Embedded Algorithm Controller (EAC)
The EAC takes commands from the host system for programming and erasing the flash memory array and
performs all the complex operations needed to change the non-volatile memory state. This frees the host
system from any need to manage the program and erase processes.
There are four EAC operation categories:
Standby (Read Mode)
Address Space Switching
Embedded Algorithms (EA)
Advanced Sector Protection (ASP) Management
5.1.1 EAC Standby
In the standby mode current consumption is greatly reduced. The EAC enters its standby mode when no
command is being processed and no Embedded Algorithm is in progress. If the device is deselected
(CE# = High) during an Embedded Algorithm, the device still draws active current until the operation is
completed (ICC3). ICC4 in DC Characteristics on page 74 represents the standby current specification when
both the Host Interface and EAC are in their Standby state.
5.1.2 Address Space Switching
Writing specific address and data sequences (command sequences) switch the memory device address
space from the main flash array to one of the Address Space Overlays (ASO).
Embedded Algorithms operate on the information visible in the currently active (entered) ASO. The system
continues to have access to the ASO until the system issues an ASO Exit command, performs a Hardware
RESET, or until power is removed from the device. An ASO Exit Command switches from an ASO back to the
main flash array address space. The commands accepted when a particular ASO is entered are listed
between the ASO enter and exit commands in the command definitions table. See Command Summary
on page 57 for address and data requirements for all command sequences.
5.1.3 Embedded Algorithms (EA)
Changing the non-volatile data in the memory array requires a complex sequence of operations that are
called Embedded Algorithms (EA). The algorithms are managed entirely by the device internal Embedded
Algorithm Controller (EAC). The main algorithms perform programming and erasing of the main array data
and the ASO’s. The host system writes command codes to the flash device address space. The EAC
receives the commands, performs all the necessary steps to complete the command, and provides status
information during the progress of an EA.

Data Sheet
5.2 Program and Erase Summary
Flash data bits are erased in parallel in a large group called a sector. The Erase operation places each data
bit in the sector in the logical 1 state (High). Flash data bits may be individually programmed from the erased
1 state to the programmed logical 0 (low) state. A data bit of 0 cannot be programmed back to a 1. A
succeeding read shows that the data is still 0. Only erase operations can convert a 0 to a 1. Programming the
same word location more than once with different 0 bits will result in the logical AND of the previous data and
the new data being programmed.
The duration of program and erase operations is shown in Embedded Algorithm Performance Table
on page 46.
Program and erase operations may be suspended.
An erase operation may be suspended to allow either programming or reading of another sector (not in the
erase sector). No other erase operation can be started during an erase suspend.
A program operation may be suspended to allow reading of another location (not in the Line being
programmed).
No other program or erase operation may be started during a suspended program operation - program or
erase commands will be ignored during a suspended program operation.
After an intervening program operation or read access is complete the suspended erase or program
operation may be resumed. The resume can happen at any time after the suspend assuming the device is
not in the process of executing another command.
Program and Erase operations may be interrupted as often as necessary but in order for a program or
erase operation to progress to completion there must be some periods of time between resume and the
next suspend commands greater than or equal to tPRS or tERS in Embedded Algorithm Performance Table
on page 46.
When an Embedded Algorithm (EA) is complete, the EAC returns to the operation state and address space
from which the EA was started (Erase Suspend or EAC Standby).
The system can determine the status of a program or erase operation by reading the Status Register or using
Data Polling Status. Refer to Status Register on page 37 for information on these status bits. Refer to Data
Polling Status on page 38 for more information.
Any commands written to the device during the Embedded Program Algorithm are ignored except the
Program Suspend, and Status Read command.
Any commands written to the device during the Embedded Erase Algorithm are ignored except Erase
Suspend and Status Read command.
A hardware reset immediately terminates any in progress program / erase operation and returns to read
mode after tRPH time. The terminated operation should be reinitiated once the device has returned to the idle
state, to ensure data integrity.
For performance and reliability reasons reading and programming is internally done on full 32-byte Pages.
ICC3 in DC Characteristics on page 74 represents the active current specification for a write (Embedded
Algorithm) operation.
5.2.1 Program Granularity
The S29GL-S supports two methods of programming, Word or Write Buffer Programming. Each Page can be
programmed by either method. Pages programmed by different methods may be mixed within a Line for the
Industrial Temperature version (-40°C to +85°C). For the In-Cabin version (-40°C to +105°C) the device will
only support one programming operation on each 32-byte page between erase operations and Single Word
Programming command is not supported.
Word programming examines the data word supplied by the command and programs 0’s in the addressed
memory array word to match the 0’s in the command data word.
Write Buffer Programming examines the write buffer and programs 0’s in the addressed memory array Pages
to match the 0’s in the write buffer. The write buffer does not need to be completely filled with data. It is
allowed to program as little as a single bit, several bits, a single word, a few words, a Page, multiple Pages, or
the entire buffer as one programming operation. Use of the write buffer method reduces host system

Data Sheet
overhead in writing program commands and reduces memory device internal overhead in programming
operations to make Write Buffer Programming more efficient and thus faster than programming individual
words with the Word Programming command.
5.2.2 Incremental Programming
The same word location may be programmed more than once, by either the Word or Write Buffer
Programming methods, to incrementally change 1’s to 0’s.
5.3 Command Set
5.3.1 Program Methods
5.3.1.1 Word Programming
Word programming is used to program a single word anywhere in the main Flash Memory Array.
The Word Programming command is a four-write-cycle sequence. The program command sequence is
initiated by writing two unlock write cycles, followed by the program set up command. The program address
and data are written next, which in turn initiate the Embedded Word Program algorithm. The system is not
required to provide further controls or timing. The device automatically generates the program pulses and
verifies the programmed cell margin internally. When the Embedded Word Program algorithm is complete,
the EAC then returns to its standby mode.
The system can determine the status of the program operation by using Data Polling Status, reading the
Status Register, or monitoring the RY/BY# output. See Status Register on page 37 for information on these
status bits. See Data Polling Status on page 38 for information on these status bits. See Figure 5.1
on page 27 for a diagram of the programming operation.
Any commands other than Program Suspend written to the device during the Embedded Program algorithm
are ignored. Note that a hardware reset (RESET# = VIL) immediately terminates the programming operation
and returns the device to read mode after tRPH time. To ensure data integrity, the Program command
sequence should be reinitiated once the device has completed the hardware reset operation.
A modified version of the Word Programming command, without unlock write cycles, is used for programming
when entered into the Lock Register, Password, and PPB ASOs. The same command is used to change
volatile bits when entered in to the PPB Lock, and DYB ASOs. See Table 6.1 on page 57 for program
command sequences.

Data Sheet
5.3.1.2 Write Buffer Programming
A write buffer is used to program data within a 512-byte address range aligned on a 512-byte boundary
(Line). Thus, a full Write Buffer Programming operation must be aligned on a Line boundary. Programming
operations of less than a full 512 bytes may start on any word boundary but may not cross a Line boundary.
At the start of a Write Buffer programming operation all bit locations in the buffer are all 1’s (FFFFh words)
thus any locations not loaded will retain the existing data. See Product Overview on page 10 for information
on address map.
Write Buffer Programming allows up to 512 bytes to be programmed in one operation. It is possible to
program from 1 bit up to 512 bytes in each Write Buffer Programming operation. It is recommended that a
multiple of Pages be written and each Page written only once. For the very best performance, programming
should be done in full Lines of 512 bytes aligned on 512-byte boundaries.
Write Buffer Programming is supported only in the main flash array or the SSR ASO.
The Write Buffer Programming operation is initiated by first writing two unlock cycles. This is followed by a
third write cycle of the Write to Buffer command with the Sector Address (SA), in which programming is to
occur. Next, the system writes the number of word locations minus 1. This tells the device how many write
buffer addresses are loaded with data and therefore when to expect the Program Buffer to flash confirm
command. The Sector Address must match in the Write to Buffer command and the Write Word Count
command. The Sector to be programmed must be unlocked (unprotected).
The system then writes the starting address / data combination. This starting address is the first address /
data pair to be programmed, and selects the write-buffer-Line address. The Sector address must match the
Write to Buffer Sector Address or the operation will abort and return to the initiating state. All subsequent
address / data pairs must be in sequential order. All write buffer addresses must be within the same Line. If
the system attempts to load data outside this range, the operation will abort and return to the initiating state.
The counter decrements for each data load operation. Note that while counting down the data writes, every
write is considered to be data being loaded into the write buffer. No commands are possible during the write
buffer loading period. The only way to stop loading the write buffer is to write with an address that is outside
the Line of the programming operation. This invalid address will immediately abort the Write to Buffer
command.
Once the specified number of write buffer locations has been loaded, the system must then write the Program
Buffer to Flash command at the Sector Address. The device then goes busy. The Embedded Program
algorithm automatically programs and verifies the data for the correct data pattern. The system is not required
to provide any controls or timings during these operations. If an incorrect number of write buffer locations
have been loaded the operation will abort and return to the initiating state. The abort occurs when anything
other than the Program Buffer to Flash is written when that command is expected at the end of the word
count.
The write-buffer embedded programming operation can be suspended using the Program Suspend
command. When the Embedded Program algorithm is complete, the EAC then returns to the EAC standby or
Erase Suspend standby state where the programming operation was started.
The system can determine the status of the program operation by using Data Polling Status, reading the
Status Register, or monitoring the RY/BY# output. See Status Register on page 37 for information on these
status bits. See Data Polling Status on page 38 for information on these status bits. See Figure 5.2
on page 29 for a diagram of the programming operation.
The Write Buffer Programming Sequence will be Aborted under the following conditions:
Load a Word Count value greater than the buffer size (255).
Write an address that is outside the Line provided in the Write to Buffer command.
The Program Buffer to Flash command is not issued after the Write Word Count number of data words is
loaded.
When any of the conditions that cause an abort of write buffer command occur the abort will happen
immediately after the offending condition, and will indicate a Program Fail in the Status Register at bit location
4 (PSB = 1) due to Write Buffer Abort bit location 3 (WBASB = 1). The next successful program operation will
clear the failure status or a Clear Status Register may be issued to clear the PSB status bit.
The Write Buffer Programming Sequence can be stopped by the following: Hardware Reset or Power cycle.
However, these using either of these methods may leave the area being programmed in an intermediate state

with invalid or unstable data values. In this case the same area will need to be reprogrammed with the same
data or erased to ensure data values are properly programmed or erased.

5.3.2 Program Suspend / Program Resume Commands
The Program Suspend command allows the system to interrupt an embedded programming operation so that
data can read from any non-suspended Line. When the Program Suspend command is written during a
programming process, the device halts the programming operation within tPSL (program suspend latency)
and updates the status bits. Addresses are don't-cares when writing the Program Suspend command.
There are two commands available for program suspend. The legacy combined Erase / Program suspend
command (B0h command code) and the separate Program Suspend command (51h command code). There
are also two commands for Program resume. The legacy combined Erase / Program resume command (30h
command code) and the separate Program Resume command (50h command code). It is recommended to
use the separate program suspend and resume commands for programming and use the legacy combined
command only for erase suspend and resume.
After the programming operation has been suspended, the system can read array data from any non-
suspended Line. The Program Suspend command may also be issued during a programming operation while
an erase is suspended. In this case, data may be read from any addresses not in Erase Suspend or Program
Suspend.
After the Program Resume command is written, the device reverts to programming and the status bits are
updated. The system can determine the status of the program operation by reading the Status Register or
using Data Polling. Refer to Status Register on page 37 for information on these status bits. Refer to Data
Polling Status on page 38 for more information.
Accesses and commands that are valid during Program Suspend are:
Read to any other non-erase-suspended sector
Read to any other non-program-suspended Line
Status Read command
Exit ASO or Command Set Exit
Program Resume command
The system must write the Program Resume command to exit the Program Suspend mode and continue the
programming operation. Further writes of the Program Resume command are ignored. Another Program
Suspend command can be written after the device has resumed programming.

Data Sheet
Program operations can be interrupted as often as necessary but in order for a program operation to progress
to completion there must be some periods of time between resume and the next suspend command greater
than or equal to tPRS in Embedded Algorithm Controller (EAC) on page 25.
Program suspend and resume is not supported while entered in an ASO. While in program suspend entry into
ASO is not supported.
5.3.3 Blank Check
The Blank Check command will confirm if the selected main flash array sector is erased. The Blank Check
command does not allow for reads to the array during the Blank Check. Reads to the array while this
command is executing will return unknown data.
To initiate a Blank Check on a Sector, write 33h to address 555h in the Sector, while the EAC is in the
standby state
The Blank Check command may not be written while the device is actively programming or erasing or
suspended.
Use the Status Register read to confirm if the device is still busy and when complete if the sector is blank or
not. Bit 7 of the Status Register will show if the device is performing a Blank Check (similar to an erase
operation). Bit 5 of the Status Register will be cleared to 0 if the sector is erased and set to 1 if not erased.
As soon as any bit is found to not be erased, the device will halt the operation and report the results.
Once the Blank Check is completed, the EAC will return to the Standby State.
5.3.4 Erase Methods
5.3.4.1 Chip Erase
The chip erase function erases the entire main Flash Memory Array. The device does not require the system
to preprogram prior to erase. The Embedded Erase algorithm automatically programs and verifies the entire
memory for an all 0 data pattern prior to electrical erase. After a successful chip erase, all locations within the
device contain FFFFh. The system is not required to provide any controls or timings during these operations.
The chip erase command sequence is initiated by writing two unlock cycles, followed by a set up command.
Two additional unlock write cycles are then followed by the chip erase command, which in turn invokes the
Embedded Erase algorithm. When WE# goes high, at the end of the 6th cycle, the RY/BY# goes low.
When the Embedded Erase algorithm is complete, the EAC returns to the standby state. Note that while the
Embedded Erase operation is in progress, the system can not read data from the device. The system can
determine the status of the erase operation by reading RY/BY#, the Status Register or using Data Polling.
Refer to Status Register on page 37 for information on these status bits. Refer to Data Polling Status
on page 38 for more information.
Once the chip erase operation has begun, only a Status Read, Hardware RESET or Power cycle are valid. All
other commands are ignored. However, a Hardware Reset or Power Cycle immediately terminates the erase
operation and returns to read mode after tRPH time. If a chip erase operation is terminated, the chip erase
command sequence must be reinitiated once the device has returned to the idle state to ensure data integrity.
See Table 5.4 on page 46, Asynchronous Write Operations on page 83 and Alternate CE# Controlled Write
Operations on page 89 for parameters and timing diagrams.
Sectors protected by the ASP DYB and PPB lock bits will not be erased. See ASP on page 19. If a sector is
protected during chip erase, chip erase will skip the protected sector and continue with next sector erase. The
status register erase status bit and sector lock bit are not set to 1 by a failed erase on a protected sector.

Data Sheet
5.3.4.2 Sector Erase
The sector erase function erases one sector in the memory array. The device does not require the system to
preprogram prior to erase. The Embedded Erase algorithm automatically programs and verifies the entire
sector for an all 0 data pattern prior to electrical erase. After a successful sector erase, all locations within the
erased sector contain FFFFh. The system is not required to provide any controls or timings during these
operations. The sector erase command sequence is initiated by writing two unlock cycles, followed by a set
up command. Two additional unlock write cycles are then followed by the address of the sector to be erased,
and the sector erase command. When WE# goes high, at the end of the 6th cycle, the RY/BY# goes low.
The system can determine the status of the erase operation by reading the Status Register or using Data
Polling. Refer to Status Register on page 37 for information on these status bits. Refer to Data Polling Status
on page 38 for more information.
Once the sector erase operation has begun, the Status Register Read and Erase Suspend commands are
valid. All other commands are ignored. However, note that a hardware reset immediately terminates the
erase operation and returns to read mode after tRPH time. If a sector erase operation is terminated, the sector
erase command sequence must be reinitiated once the device has reset operation to ensure data integrity.
See Embedded Algorithm Controller (EAC) on page 25 for parameters and timing diagrams.
Sectors protected by the ASP DYB and PPB lock bits will not be erased. See ASP on page 19.

5.3.5 Erase Suspend / Erase Resume
The Erase Suspend command allows the system to interrupt a sector erase operation and then read data
from, or program data to, the main flash array. This command is valid only during sector erase or program
operation. The Erase Suspend command is ignored if written during the chip erase operation.
When the Erase Suspend command is written during the sector erase operation, the device requires a
maximum of tESL (erase suspend latency) to suspend the erase operation and update the status bits.
After the erase operation has been suspended, the part enters the erase-suspend mode. The system can
read data from or program data to the main flash array. Reading at any address within erase-suspended
sectors produces undetermined data. The system can determine if a sector is actively erasing or is erase-
suspended by reading the Status Register or using Data Polling. Refer to Status Register on page 37 for
information on these status bits. Refer to Data Polling Status on page 38 for more information.
After an erase-suspended program operation is complete, the EAC returns to the erase-suspend state. The
system can determine the status of the program operation by reading the Status Register, just as in the
standard program operation.
If a program failure occurs during erase suspend the Clear or Reset commands will return the device to the
erase suspended state. Erase will need to be resumed and completed before again trying to program the
memory array.
Accesses and commands that are valid during Erase Suspend are:
Read to any other non-suspended sector
Program to any other non-suspended sector
Status Register Read
Status Register Clear
Enter DYB ASO
DYB Set
DYB Clear
DYB Status Read
Exit ASO or Command Set Exit
Erase Resume command
To resume the sector erase operation, the system must write the Erase Resume command. The device will
revert to erasing and the status bits will be updated. Further writes of the Resume command are ignored.
Another Erase Suspend command can be written after the chip has resumed erasing.
Erase suspend and resume is not supported while entered in an ASO. While in erase suspend entry into ASO
is not supported.

5.3.6 ASO Entry and Exit
5.3.6.1 ID-CFI ASO
The system can access the ID-CFI ASO by issuing the ID-CFI Entry command sequence during Read Mode.
This entry command uses the Sector Address (SA) in the command to determine which sector will be overlaid
and which sector's protection state is reported in word location 2h. See the detail description Table 6.2
on page 60.
The ID-CFI ASO allows the following activities:
Read ID-CFI ASO, using the same SA as used in the entry command.
Read Sector Protection State at Sector Address (SA) + 2h. Location 2h provides volatile information on the
current state of sector protection for the sector addressed. Bit 0 of the word at location 2h shows the logical
NAND of the PPB and DYB bits related to the addressed sector such that if the sector is protected by either
the PPB=0 or the DYB=0 bit for that sector the state shown is protected. (1= Sector protected, 0= Sector
unprotected). This protection state is shown only for the SA selected when entering ID-CFI ASO. Reading
other SA provides undefined data. To read a different SA protection state ASO exit command must be used
and then enter ID-CFI ASO again with the new SA.
ASO Exit.
The following is a C source code example of using the CFI Entry and Exit functions. Refer to the Spansion
Low Level Driver User's Guide (available on www.spansion.com) for general information on Spansion flash
memory software development guidelines.
/* Example: CFI Entry command */
*( (UINT16 *)base_addr + 0x55 ) = 0x0098; /* write CFI entry command */
/* Example: CFI Exit command */
*( (UINT16 *)base_addr + 0x000 ) = 0x00F0; /* write cfi exit command */
5.3.6.2 Status Register ASO
The Status Register ASO contains a single word of registered volatile status for Embedded Algorithms. When
the Status Register read command is issued, the current status is captured (by the rising edge of WE#) into
the register and the ASO is entered. The Status Register content appears on all word locations. The first read
access exits the Status Register ASO (with the rising edge of CE# or OE#) and returns to the address space
map in use when the Status Register read command was issued. Write commands will not exit the Status
Register ASO state.
5.3.6.3 Secure Silicon Region ASO
The system can access the Secure Silicon Region by issuing the Secure Silicon Region Entry command
sequence during Read Mode. This entry command uses the Sector Address (SA) in the command to
determine which sector will be overlaid.
The Secure Silicon Region ASO allows the following activities:
Read Secure Silicon Regions.
Programming the customer Secure Silicon Region is allowed using the Word or Write Buffer Programming
commands.
ASO Exit using legacy Secure Silicon Exit command for backward software compatibility.
ASO Exit using the common exit command for all ASO - alternative for a consistent exit method.

5.3.6.4 Lock Register ASO
The system can access the Lock Register by issuing the Lock Register entry command sequence during
Read Mode. This entry command does not use a sector address from the entry command. The Lock Register
appears at word location 0 in the device address space. All other locations in the device address space are
undefined.
The Lock Register ASO allows the following activities:
Read Lock Register, using device address location 0.
Program the customer Lock Register using a modified Word Programming command.
ASO Exit using legacy Command Set Exit command for backward software compatibility.
ASO Exit using the common exit command for all ASO - alternative for a consistent exit method.
5.3.6.5 Password ASO
The system can access the Password ASO by issuing the Password entry command sequence during Read
Mode. This entry command does not use a sector address from the entry command. The Password appears
at word locations 0 to 3 in the device address space. All other locations in the device address space are
undefined.
The Password ASO allows the following activities:
Read Password, using device address location 0 to 3.
Program the Password using a modified Word Programming command.
Unlock the PPB Lock bit with the Password Unlock command.
ASO Exit using legacy Command Set Exit command for backward software compatibility.
ASO Exit using the common exit command for all ASO - alternative for a consistent exit method.
5.3.6.6 PPB ASO
The system can access the PPB ASO by issuing the PPB entry command sequence during Read Mode. This
entry command does not use a sector address from the entry command. The PPB bit for a sector appears in
bit 0 of all word locations in the sector.
The PPB ASO allows the following activities:
Read PPB protection status of a sector in bit 0 of any word in the sector.
Program the PPB bit using a modified Word Programming command.
Erase all PPB bits with the PPB erase command.
ASO Exit using legacy Command Set Exit command for backward software compatibility.
ASO Exit using the common exit command for all ASO - alternative for a consistent exit method.
5.3.6.7 PPB Lock ASO
The system can access the PPB Lock ASO by issuing the PPB Lock entry command sequence during Read
Mode. This entry command does not use a sector address from the entry command. The global PPB Lock bit
appears in bit 0 of all word locations in the device.
The PPB Lock ASO allows the following activities:
Read PPB Lock protection status in bit 0 of any word in the device address space.
Set the PPB Lock bit using a modified Word Programming command.
ASO Exit using legacy Command Set Exit command for backward software compatibility.
ASO Exit using the common exit command for all ASO - alternative for a consistent exit method.

5.3.6.8 DYB ASO
The system can access the DYB ASO by issuing the DYB entry command sequence during Read Mode. This
entry command does not use a sector address from the entry command. The DYB bit for a sector appears in
bit 0 of all word locations in the sector.
The DYB ASO allows the following activities:
Read DYB protection status of a sector in bit 0 of any word in the sector.
Set the DYB bit using a modified Word Programming command.
Clear the DYB bit using a modified Word Programming command.
ASO Exit using legacy Command Set Exit command for backward software compatibility.
ASO Exit using the common exit command for all ASO - alternative for a consistent exit method.
5.3.6.9 Software (Command) Reset / ASO exit
Software reset is part of the command set (See Table 6.1, Command Definitions on page 57) that also
returns the EAC to standby state and must be used for the following conditions:
Exit ID/CFI mode
Clear timeout bit (DQ5) for data polling when timeout occurs
Software Reset does not affect EA mode. Reset commands are ignored once programming or erasure has
begun, until the operation is complete. Software Reset does not affect outputs; it serves primarily to return to
Read Mode from an ASO mode or from a failed program or erase operation.
Software Reset may cause a return to Read Mode from undefined states that might result from invalid
command sequences. However, a Hardware Reset may be required to return to normal operation from some
undefined states.
There is no software reset latency requirement. The reset command is executed during the tWPH period.
5.4 Status Monitoring
There are three methods for monitoring EA status. Previous generations of the S29GL flash family used the
methods called Data Polling and Ready/Busy# (RY/BY#) Signal. These methods are still supported by the
S29GL-S family. One additional method is reading the Status Register.
5.4.1 Status Register
The status of program and erase operations is provided by a single 16-bit status register. The status is
receiver by writing the Status Register Read command followed by a read access. When the Status Register
read command is issued, the current status is captured (by the rising edge of WE#) into the register and the
ASO is entered. The contents of the status register is aliased (overlaid) on the full memory address space.
Any valid read (CE# and OE# low) access while in the Status Register ASO will exit the ASO (with the rising
edge of CE# or OE# for tCEPH/tOEPH time) and return to the address space map in use when the Status
Register Read command was issued.
The status register contains bits related to the results - success or failure - of the most recently completed
Embedded Algorithms (EA):
Erase Status (bit 5),
Program Status (bit 4),
Write Buffer Abort (bit 3),
Sector Locked Status (bit 1),
RFU (bit 0).
and, bits related to the current state of any in process EA:
Device Busy (bit 7),
Erase Suspended (bit 6),
38 GL-S MirrorBit®Family S29GL_128S_01GS_00_08 October 9, 2013
Data Sheet
Program Suspended (bit 2),
The current state bits indicate whether an EA is in process, suspended, or completed.
The upper 8 bits (bits 15:8) are reserved. These have undefined High or Low value that can change from one
status read to another. These bits should be treated as don't care and ignored by any software reading status.
The Soft Reset Command will clear to 0 bits [5, 4, 1, 0] of the status register if Status Register bit 3 =0. It will
not affect the current state bits. The Clear Status Register Command will clear to 0 the results related bits of
the status register but will not affect the current state bits.
Notes:
1. Bits 15 thru 8, and 0 are reserved for future use and may display as 0 or 1. These bits should be ignored (masked) when checking status.
2. Bit 7 is 1 when there is no Embedded Algorithm in progress in the device.
3. Bits 6 thru 1 are valid only if Bit 7 is 1.
4. All bits are put in their reset status by cold reset or warm reset.
5. Bits 5, 4, 3, and 1 are cleared to 0 by the Clear Status Register command or Reset command.
6. Upon issuing the Erase Suspend Command, the user must continue to read status until DRB becomes 1.
7. ESSB is cleared to 0 by the Erase Resume Command.
8. ESB reflects success or failure of the most recent erase operation.
9. PSB reflects success or failure of the most recent program operation.
10. During erase suspend, programming to the suspended sector, will cause program failure and set the Program status bit to 1.
11. Upon issuing the Program Suspend Command, the user must continue to read status until DRB becomes 1.
12. PSSB is cleared to 0 by the Program Resume Command.
13. SLSB indicates that a program or erase operation failed because the sector was locked.
14. SLSB reflects the status of the most recent program or erase operation.
5.4.2 Data Polling Status
During an active Embedded Algorithm the EAC switches to the Data Polling ASO to display EA status to any
read access. A single word of status information is aliased in all locations of the device address space. In the
status word there are several bits to determine the status of an EA. These are referred to as DQ bits as they
appear on the data bus during a read access while an EA is in progress. DQ bits 15 to 8, DQ4, and DQ0 are
reserved and provide undefined data. Status monitoring software must mask the reserved bits and treat them
as don't care. Table 5.3 on page 42 and the following subsections describe the functions of the remaining
bits.

Data Sheet
5.4.2.1 DQ7: Data# Polling
The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Algorithm is in progress or
has completed. Data# Polling is valid after the rising edge of the final WE# pulse in the program or erase
command sequence. Note that the Data# Polling is valid only for the last word being programmed in the write-
buffer-page during Write Buffer Programming. Reading Data# Polling status on any word other than the last
word to be programmed in the write-buffer-page will return false status information.
During the Embedded Program algorithm, the device outputs on DQ7 the complement of the data bit
programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When the
Embedded Program algorithm is complete, the device outputs the data bit programmed to bit 7 of the last
word programmed. In case of a Program Suspend, the device allows only reading array data. If a program
address falls within a protected sector, Data# Polling on DQ7 is active for approximately 20 µs, then the
device returns to reading array data.
During the Embedded Erase or Blank Check algorithms, Data# Polling produces a 0 on DQ7. When the
algorithm is complete, or if the device enters the Erase Suspend mode, Data# Polling produces a 1 on DQ7.
This is analogous to the complement / true datum output described for the Embedded Program algorithm: the
erase function changes all the bits in a sector to 1; prior to this, the device outputs the complement or '0'. The
system must provide an address within the sector selected for erasure to read valid status information on
DQ7.
After an erase command sequence is written, if the sector selected for erasing is protected, Data# Polling on
DQ7 is active for approximately 100 µs, then the device returns to reading array data.
When the system detects DQ7 has changed from the complement to true data, it can read valid data at
DQ15-DQ0 on the following read cycles. This is because DQ7 may change asynchronously with DQ6-DQ0
while Output Enable (OE#) is asserted Low. This is illustrated in Figure 10.16 on page 88. Table 5.3
on page 42 shows the outputs for Data# polling on DQ7. Figure 5.2 on page 29 shows the Data# polling
algorithm use in Write Buffer Programming.
Valid DQ7 data polling status may only be read from:
the address of the last word loaded into the Write Buffer for a Write Buffer programming operation;
the location of a single word programming operation;
or a location in a sector being erased or blank checked;
or a location in any sector during chip erase.

Note:
1. DQ7 should be rechecked even if DQ5 = 1 because DQ7 may change simultaneously with DQ5.

5.4.2.2 DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete,
or whether the device has entered the Program Suspend or Erase Suspend mode. Toggle Bit I may be read
at any address, and is valid after the rising edge of the final WE# pulse in the command sequence (prior to the
program or erase operation).
During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause
DQ6 to toggle. (The system may use either OE# or CE# to control the read cycles). When the operation is
complete, DQ6 stops toggling.
After an erase command sequence is written, if the sector selected for erasing is protected, DQ6 toggles for
approximately 100 µs, then the EAC returns to standby (Read Mode). If the selected sector is not protected,
the Embedded Erase algorithm erases the unprotected sector.
The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or erase-
suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6
toggles. When the device enters the Program Suspend mode or Erase Suspend mode, DQ6 stops toggling.
However, the system must also use DQ2 to determine which sectors are erasing, or erase-suspended.
Alternatively, the system can use DQ7 (see DQ7: Data# Polling on page 39).
DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program
algorithm is complete.
Table 5.3 on page 42 shows the outputs for Toggle Bit I on DQ6. Figure 5.6 on page 41 shows the toggle bit
algorithm in flowchart form, and the Reading Toggle Bits DQ6/DQ2 on page 41 explains the algorithm.
Figure 5.6 on page 41 shows the toggle bit timing diagrams. Figure 5.2 on page 29 shows the differences
between DQ2 and DQ6 in graphical form. See also DQ2: Toggle Bit II on page 40.
5.4.2.3 DQ3: Sector Erase Timer
After writing a sector erase command sequence, the system may read DQ3 to determine whether or not
erasure has begun. See Sector Erase on page 33 for more details.
After the sector erase command is written, the system should read the status of DQ7 (Data# Polling) or DQ6
(Toggle Bit I) to ensure that the device has accepted the command sequence, and then read DQ3. If DQ3 is
1, the Embedded Erase algorithm has begun; all further commands (except Erase Suspend) are ignored until
the erase operation is complete. Table 5.3 on page 42 shows the status of DQ3 relative to the other status
bits.
5.4.2.4 DQ2: Toggle Bit II
Toggle Bit II on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that is,
the Embedded Erase algorithm is in progress), or whether that sector is erase-suspended. Toggle Bit II is
valid after the rising edge of the final WE# pulse in the command sequence.
DQ2 toggles when the system reads at addresses within the sector selected for erasure. (The system may
use either OE# or CE# to control the read cycles). But DQ2 cannot distinguish whether the sector is actively
erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is actively erasing, or is in
Erase Suspend, but cannot distinguish if the sector is selected for erasure. Thus, both status bits are required
for sector and mode information. Refer to Table 5.3 on page 42 to compare outputs for DQ2 and DQ6.
Figure 5.5 on page 39 shows the toggle bit algorithm in flowchart form, and the Reading Toggle Bits DQ6/
DQ2 on page 41 explains the algorithm. See also Figure 5.6 on page 41 shows the toggle bit timing diagram.
Figure 5.2 on page 29 shows the differences between DQ2 and DQ6 in graphical form.

5.4.2.5 Reading Toggle Bits DQ6/DQ2
Refer to Figure 5.5 on page 39 for the following discussion. Whenever the system initially begins reading
toggle bit status, it must read DQ7-DQ0 at least twice in a row to determine whether a toggle bit is toggling.
Typically, the system would note and store the value of the toggle bit after the first read. After the second
read, the system would compare the new value of the toggle bit with the previous value. If the toggle bit is not
toggling, the device has completed the program or erases operation. The system can read array data on
DQ15-DQ0 on the following read cycle.
However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the
system also should note whether the value of DQ5 is High (see DQ5: Exceeded Timing Limits on page 41). If
it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have
stopped toggling just as DQ5 went High. If the toggle bit is no longer toggling, the device has successfully
completed the program or erase operation. If it is still toggling, the device did not complete the operation
successfully, and the system must write the reset command to return to reading array data.
The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not
gone High. The system may continue to monitor the toggle bit and DQ5 through successive read cycles,
determining the status as described in the previous paragraph. Alternatively, it may choose to perform other
system tasks. In this case, the system must start at the beginning of the algorithm when it returns to
determine the status of the operation (top of Figure 5.6 on page 41).
Figure 5.6 Toggle Bit Program
Notes:
1. Read toggle bit twice to determine whether or not it is toggling. See text.
2. Recheck toggle bit because it may stop toggling as DQ5 changes to 1. See text.
5.4.2.6 DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under
these conditions DQ5 produces a 1. This is a failure condition that indicates the program or erase cycle was
not successfully completed. The system must issue the reset command to return the device to reading array
data.
When a timeout occurs, the software must send a reset command to clear the timeout bit (DQ5) and to return
the EAC to read array mode. In this case, it is possible that the flash will continue to communicate busy for up
to 2 µs after the reset command is sent.

5.4.2.7 DQ1: Write-to-Buffer Abort
DQ1 indicates whether a Write-to-Buffer operation was aborted. Under these conditions DQ1 produces a 1.
The system must issue the Write-to-Buffer-Abort-Reset command sequence to return the EAC to standby
(Read Mode) and the Status Register failed bits are cleared. See Write Buffer Programming on page 28 for
more details.
Notes:
1. DQ5 switches to '1' when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits. See DQ5:
Exceeded Timing Limits on page 41 for more information.
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details.
3. Data are invalid for addresses in a Program Suspended Line. All addresses other than the program suspended line can be read for valid
data.
4. DQ1 indicates the Write-to-Buffer ABORT status during Write-Buffer-Programming operations.
5. Applies only to program operations.
5.5 Error Types and Clearing Procedures
There are three types of errors reported by the embedded operation status methods. Depending on the error
type, the status reported and procedure for clearing the error status is different. Following is the clearing of
error status:
If an ASO was entered before the error the device remains entered in the ASO awaiting ASO read or
a command write.
If an erase was suspended before the error the device returns to the erase suspended state awaiting
flash array read or a command write.
Otherwise, the device will be in standby state awaiting flash array read or a command write.

5.5.1 Embedded Operation Error
If an error occurs during an embedded operation (program, erase, blank check, or password unlock) the
device (EAC) remains busy. The RY/BY# output remains Low, data polling status continues to be overlaid on
all address locations, and the status register shows ready with valid status bits. The device remains busy until
the error status is detected by the host system status monitoring and the error status is cleared.
During embedded algorithm error status the Data Polling status will show the following:
DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer or last word of the
password in the case of the password unlock command. DQ7 = 0 for an erase or blank check failure
DQ6 continues to toggle
DQ5 = 1; Failure of the embedded operation
DQ4 is RFU and should be treated as don’t care (masked)
DQ3 = 1 to indicate embedded sector erase in progress
DQ2 continues to toggle, independent of the address used to read status
DQ1 = 0; Write buffer abort error
DQ0 is RFU and should be treated as don’t care (masked)
During embedded algorithm error status the Status Register will show the following:
SR[7] = 1; Valid status displayed
SR[6] = X; May or may not be erase suspended during the EA error
SR[5] = 1 on erase or blank check error; else = 0
SR[4] = 1 on program or password unlock error; else = 0
SR[3] = 0; Write buffer abort
SR[2] = 0; Program suspended
SR[1] = 0; Protected sector
SR[0] = X; RFU, treat as don’t care (masked)
When the embedded algorithm error status is detected, it is necessary to clear the error status in order to
return to normal operation, with RY/BY# High, ready for a new read or command write. The error status can
be cleared by writing:
Reset command
Status Register Clear command
Commands that are accepted during embedded algorithm error status are:
Status Register Read
Reset command
Status Register Clear command

5.5.2 Protection Error
If an embedded algorithm attempts to change data within a protected area (program, or erase of a protected
sector or OTP area) the device (EAC) goes busy for a period of 20 to 100 µs then returns to normal operation.
During the busy period the RY/BY# output remains Low, data polling status continues to be overlaid on all
address locations, and the status register shows not ready with invalid status bits (SR[7] = 0).
During the protection error status busy period the data polling status will show the following:
DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer. DQ7 = 0 for an erase
failure
DQ6 continues to toggle, independent of the address used to read status
DQ5 = 0; to indicate no failure of the embedded operation during the busy period
DQ4 is RFU and should be treated as don’t care (masked)
DQ3 = 1 to indicate embedded sector erase in progress
DQ2 continues to toggle, independent of the address used to read status
DQ1 = 0; Write buffer abort error
DQ0 is RFU and should be treated as don’t care (masked)
Commands that are accepted during the protection error status busy period are:
Status Register Read
When the busy period ends the device returns to normal operation, the data polling status is no longer
overlaid, RY/BY# is High, and the status register shows ready with valid status bits. The device is ready for
flash array read or write of a new command.
After the protection error status busy period the Status Register will show the following:
SR[7] = 1; Valid status displayed
SR[6] = X; May or may not be erase suspended after the protection error busy period
SR[5] = 1 on erase error, else = 0
SR[4] = 1 on program error, else = 0
SR[3] = 0; Program not aborted
SR[2] = 0; No Program in suspension
SR[1] = 1; Error due to attempting to change a protected location
SR[0] = X; RFU, treat as don’t care (masked)
Commands that are accepted after the protection error status busy period are:
Any command

5.5.3 Write Buffer Abort
If an error occurs during a Write to Buffer command the device (EAC) remains busy. The RY/BY# output
remains Low, data polling status continues to be overlaid on all address locations, and the status register
shows ready with valid status bits. The device remains busy until the error status is detected by the host
system status monitoring and the error status is cleared.
During write to buffer abort (WBA) error status the Data Polling status will show the following:
DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer
DQ6 continues to toggle, independent of the address used to read status
DQ5 = 0; to indicate no failure of the programming operation. WBA is an error in the values input by
the Write to Buffer command before the programming operation can begin
DQ4 is RFU and should be treated as don’t care (masked)
DQ3 is don't care after program operation as no erase is in progress. If the Write Buffer Program
operation was started after an erase operation had been suspended then DQ3 = 1. If there was no
erase operation in progress then DQ3 is a don't care and should be masked.
DQ2 does not toggle after program operation as no erase is in progress. If the Write Buffer Program
operation was started after an erase operation had been suspended then DQ2 will toggle in the
sector where the erase operation was suspended and not in any other sector. If there was no erase
operation in progress then DQ2 is a don't care and should be masked.
DQ1 = 1: Write buffer abort error
DQ0 is RFU and should be treated as don’t care (masked)
During embedded algorithm error status the Status Register will show the following:
SR[7] = 1; Valid status displayed
SR[6] = X; May or may not be erase suspended during the WBA error status
SR[5] = 0; Erase successful
SR[4] = 1; Programming related error
SR[3] = 1; Write buffer abort
SR[2] = 0; No Program in suspension
SR[1] = 0; Sector not locked during operation
SR[0] = X; RFU, treat as don’t care (masked)
When the WBA error status is detected, it is necessary to clear the error status in order to return to normal
operation, with RY/BY# High, ready for a new read or command write. The error status can be cleared and
device returned to normal operation by writing:
Write Buffer Abort Reset command
– Clears the status register and returns to normal operation

Legend:
X = Don't care.
RA = Address of the memory to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed.
PD = Data to be programmed at location PA.
SA = Address of the sector selected. Address bits AMAX-A16 uniquely select any sector.
WBL = Write Buffer Location. The address must be within the same Line.
WC = Word Count is the number of write buffer locations to load minus 1.
PWAx = Password address for word0 = 00h, word1 = 01h, word2 = 02h, and word3 = 03h.
PWDx = Password data word0, word1, word2, and word3.
Notes:
1. See Table 8.1, Interface States on page 67 for description of bus operations.
2. All values are in hexadecimal.
3. Except for the following, all bus cycles are write cycle: read cycle during Read, ID/CFI Read (Manufacturing ID / Device ID), Indicator Bits,
Secure Silicon Region Read, SSR Lock Read, and 2nd cycle of Status Register Read .
4. Data bits DQ15-DQ8 are don't care in command sequences, except for RD, PD, WC and PWD.
5. Address bits AMAX-A11 are don't cares for unlock and command cycles, unless SA or PA required. (AMAX is the Highest Address pin.).
6. No unlock or command cycles required when reading array data.
7. The Reset command is required to return to reading array data when device is in the ID-CFI (autoselect) mode, or if DQ5 goes High
(while the device is providing status data).
8. Command is valid when device is ready to read array data or when device is in ID-CFI (autoselect) mode.
9. The system can read and program/program suspend in non-erasing sectors, or enter the ID-CFI ASO, when in the Erase Suspend mode.
The Erase Suspend command is valid only during a sector erase operation.
10. The Erase Resume/Program Resume command is valid only during the Erase Suspend/Program Suspend modes.
11. Issue this command sequence to return to READ mode after detecting device is in a Write-to-Buffer-Abort state. IMPORTANT: the full
command sequence is required if resetting out of ABORT.
12. The Exit command returns the device to reading the array.
13. The password portion can be entered or read in any order as long as the entire 64-bit password is entered or read.
14. For PWDx, only one portion of the password can be programmed per each A0 command. Portions of the password must be programmed
in sequential order (PWD0 - PWD3).
15. All Lock Register bits are one-time programmable. The program state = 0 and the erase state = 1. Also, both the Persistent Protection
Mode Lock Bit and the Password Protection Mode Lock Bit cannot be programmed at the same time or the Lock Register Bits Program
operation aborts and returns the device to read mode. Lock Register bits that are reserved for future use are undefined and may be 0’s or
1's.
16. If any of the Entry commands was issued, an Exit command must be issued to reset the device into read mode.
17. Protected State = 00h, Unprotected State = 01h. The sector address for DYB set, DYB clear, or PPB Program command may be any
location within the sector - the lower order bits of the sector address are don't care.

6.2 Device ID and Common Flash Interface (ID-CFI) ASO Map
The Device ID portion of the ASO (word locations 0h to 0Fh) provides manufacturer ID, device ID, Sector
Protection State, and basic feature set information for the device.
ID-CFI Location 02h displays sector protection status for the sector selected by the sector address (SA) used
in the ID-CFI enter command. To read the protection status of more than one sector it is necessary to exit the
ID ASO and enter the ID ASO using the new SA. The access time to read location 02h is always tACC and a
read of this location requires CE# to go High before the read and return Low to initiate the read
(asynchronous read access). Page mode read between location 02h and other ID locations is not supported.
Page mode read between ID locations other than 02h is supported.
For additional information see ID-CFI ASO on page 35.

Data Sheet
7.4 Ready/Busy# (RY/BY#)
RY/BY# is a dedicated, open drain output pin that indicates whether an Embedded Algorithm, Power-On
Reset (POR), or Hardware Reset is in progress or complete. The RY/BY# status is valid after the rising edge
of the final WE# pulse in a command sequence, when VCC is above VCC minimum during POR, or after the
falling edge of RESET#. Since RY/BY# is an open drain output, several RY/BY# pins can be tied together in
parallel with a pull up resistor to VIO.
If the output is Low (Busy), the device is actively erasing, programming, or resetting. (This includes
programming in the Erase Suspend mode). If the output is High (Ready), the device is ready to read data
(including during the Erase Suspend mode), or is in the standby mode.
Table 5.3, Data Polling Status on page 42 shows the outputs for RY/BY# in each operation.
If an Embedded algorithm has failed (Program / Erase failure as result of max pulses or Sector is locked),
RY/BY# will stay Low (busy) until status register bits 4 and 5 are cleared and the reset command is issued.
This includes Erase or Programming on a locked sector.
7.5 Hardware Reset
The RESET# input provides a hardware method of resetting the device to standby state. When RESET# is
driven Low for at least a period of tRP, the device immediately:
terminates any operation in progress,
exits any ASO,
tristates all outputs,
resets the Status Register,
resets the EAC to standby state.
CE# is ignored for the duration of the reset operation (tRPH).
To meet the Reset current specification (ICC5) CE# must be held High.
To ensure data integrity any operation that was interrupted should be reinitiated once the device is ready to
accept another command sequence.

8. Signal Protocols
The following sections describe the host system interface signal behavior and timing for the 29GL-S family
flash devices.
8.1 Interface States
Table 8.1 describes the required value of each interface signal for each interface state.
Legend:
L = VIL
H = VIH
X = either VIL or VIH
L/H = rising edge
H/L = falling edge
Valid = all bus signals have stable L or H level
Modified = valid state different from a previous valid state
Available = read data is internally stored with output driver controlled by OE#
Notes:
1. WE# and OE# can not be at VIL at the same time.
2. Read with Output Disable is a read initiated with OE# High.
3. Automatic Sleep is a read/write operation where data has been driven on the bus for an extended period, without CE# going High and the
device internal logic has gone into standby mode to conserve power.
8.2 Power-Off with Hardware Data Protection
The memory is considered to be powered off when the core power supply (VCC) drops below the lock-out
voltage (VLKO). When VCC is below VLKO, the entire memory array is protected against a program or erase
operation. This ensures that no spurious alteration of the memory content can occur during power transition.
During a power supply transition down to Power-Off, VIO should remain less than or equal to VCC.
If VCC goes below VRST (Min) then returns above VRST (Min) to VCC minimum, the Power-On Reset interface
state is entered and the EAC starts the Cold Reset Embedded Algorithm.

Data Sheet
8.3 Power Conservation Modes
8.3.1 Interface Standby
Standby is the default, low power, state for the interface while the device is not selected by the host for data
transfer (CE# = High). All inputs are ignored in this state and all outputs except RY/BY# are high impedance.
RY/BY# is a direct output of the EAC, not controlled by the Host Interface.
8.3.2 Automatic Sleep
The automatic sleep mode reduces device interface energy consumption to the sleep level (ICC6) following
the completion of a random read access time. The device automatically enables this mode when addresses
remain stable for tACC + 30 ns. While in sleep mode, output data is latched and always available to the
system. Output of the data depends on the level of the OE# signal but, the automatic sleep mode current is
independent of the OE# signal level. Standard address access timings (tACC or tPAC C ) provide new data when
addresses are changed. ICC6 in DC Characteristics on page 74 represents the automatic sleep mode current
specification.
Automatic sleep helps reduce current consumption especially when the host system clock is slowed for power
reduction. During slow system clock periods, read and write cycles may extend many times their length
versus when the system is operating at high speed. Even though CE# may be Low throughout these
extended data transfer cycles, the memory device host interface will go to the Automatic Sleep current at tACC
+ 30 ns. The device will remain at the Automatic Sleep current for tASSB. Then the device will transition to the
standby current level. This keeps the memory at the Automatic Sleep or standby power level for most of the
long duration data transfer cycles, rather than consuming full read power all the time that the memory device
is selected by the host system.
However, the EAC operates independent of the automatic sleep mode of the host interface and will continue
to draw current during an active Embedded Algorithm. Only when both the host interface and EAC are in their
standby states is the standby level current achieved.
8.4 Read
8.4.1 Read With Output Disable
When the CE# signal is asserted Low, the host system memory controller begins a read or write data transfer.
Often there is a period at the beginning of a data transfer when CE# is Low, Address is valid, OE# is High,
and WE# is High. During this state a read access is assumed and the Random Read process is started while
the data outputs remain at high impedance. If the OE# signal goes Low, the interface transitions to the
Random Read state, with data outputs actively driven. If the WE# signal is asserted Low, the interface
transitions to the Write state. Note, OE# and WE# should never be Low at the same time to ensure no data
bus contention between the host system and memory.
October 9, 2013 S29GL_128S_01GS_00_08 GL-S MirrorBit®Family 69
Data Sheet
8.4.2 Random (Asynchronous) Read
When the host system interface selects the memory device by driving CE# Low, the device interface leaves
the Standby state. If WE# is High when CE# goes Low, a random read access is started. The data output
depends on the address map mode and the address provided at the time the read access is started.
The data appears on DQ15-DQ0 when CE# is Low, OE# is Low, WE# remains High, address remains stable,
and the asynchronous access times are satisfied. Address access time (tACC) is equal to the delay from
stable addresses to valid output data. The chip enable access time (tCE) is the delay from stable CE# to valid
data at the outputs. In order for the read data to be driven on to the data outputs the OE# signal must be Low
at least the output enable time (tOE) before valid data is available.
At the completion of the random access time from CE# active (tCE), address stable (tACC), or OE# active
(tOE), whichever occurs latest, the data outputs will provide valid read data from the currently active address
map mode. If CE# remains Low and any of the AMAX to A4 address signals change to a new value, a new
random read access begins. If CE# remains Low and OE# goes High the interface transitions to the Read
with Output Disable state. If CE# remains Low, OE# goes High, and WE# goes Low, the interface transitions
to the Write state. If CE# returns High, the interface goes to the Standby state. Back to Back accesses, in
which CE# remains Low between accesses, requires an address change to initiate the second access.
See Asynchronous Read Operations on page 80.
8.4.3 Page Read
After a Random Read access is completed, if CE# remains Low, OE# remains Low, the AMAX to A4 address
signals remain stable, and any of the A3 to A0 address signals change, a new access within the same Page
begins. The Page Read completes much faster (tPAC C ) than a Random Read access.
8.5 Write
8.5.1 Asynchronous Write
When WE# goes Low after CE is Low, there is a transition from one of the read states to the Write state. If
WE# is Low before CE# goes Low, there is a transition from the Standby state directly to the Write state
without beginning a read access.
When CE# is Low, OE# is High, and WE# goes Low, a write data transfer begins. Note, OE# and WE# should
never be Low at the same time to ensure no data bus contention between the host system and memory.
When the asynchronous write cycle timing requirements are met the WE# can go High to capture the address
and data values in to EAC command memory.
Address is captured by the falling edge of WE# or CE#, whichever occurs later. Data is captured by the rising
edge of WE# or CE#, whichever occurs earlier.
When CE# is Low before WE# goes Low and stays Low after WE# goes High, the access is called a WE#
controlled Write. When WE# is High and CE# goes High, there is a transition to the Standby state. If CE#
remains Low and WE# goes High, there is a transition to the Read with Output Disable state.
When WE# is Low before CE# goes Low and remains Low after CE# goes High, the access is called a CE#
controlled Write. A CE# controlled Write transitions to the Standby state.
If WE# is Low before CE# goes Low, the write transfer is started by CE# going Low. If WE# is Low after CE#
goes High, the address and data are captured by the rising edge of CE#. These cases are referred to as CE#
controlled write state transitions.
Write followed by Read accesses, in which CE# remains Low between accesses, requires an address
change to initiate the following read access.
Back to Back accesses, in which CE# remains Low between accesses, requires an address change to initiate
the second access.
The EAC command memory array is not readable by the host system and has no ASO. The EAC examines
the address and data in each write transfer to determine if the write is part of a legal command sequence.
When a legal command sequence is complete the EAC will initiate the appropriate EA.

8.5.2 Write Pulse “Glitch” Protection
Noise pulses of less than 5 ns (typical) on WE# will not initiate a write cycle.
8.5.3 Logical Inhibit
Write cycles are inhibited by holding OE# at VIL, or CE# at VIH, or WE# at VIH. To initiate a write cycle, CE#
and WE# must be Low (VIL) while OE# is High (VIH).

9. Electrical Specifications
9.1 Absolute Maximum Ratings
Notes:
1. Minimum DC voltage on input or I/O pins is -0.5V. During voltage transitions, input or I/O pins may undershoot VSS to -2.0V for periods of
up to 20 ns. See Figure 9.3 on page 73. Maximum DC voltage on input or I/O pins is VCC +0.5V. During voltage transitions, input or I/O
pins may overshoot to VCC +2.0V for periods up to 20 ns. See Figure 9.4 on page 73
2. No more than one output may be shorted to ground at a time. Duration of the short circuit should not be greater than one second.
3. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only;
functional operation of the device at these or any other conditions above those indicated in the operational sections of this data sheet is
not implied. Exposure of the device to absolute maximum rating conditions for extended periods may affect device reliability.

This product complies with JEDEC standard JESD78C latchup testing requirements.
9.3 Operating Ranges
9.3.1 Temperature Ranges
Industrial (I) Devices
Ambient Temperature (TA) -40°C to +85°C
9.3.2 Power Supply Voltages
VCC 2.7V to 3.6V
VIO 1.65V to VCC + 200 mV
Operating ranges define those limits between which the functionality of the device is guaranteed.
9.3.3 Power-Up and Power-Down
During power-up or power-down VCC must always be greater than or equal to VIO (VCC ≥ VIO).
The device ignores all inputs until a time delay of tVCS has elapsed after the moment that VCC and VIO both
rise above, and stay above, the minimum VCC and VIO thresholds. During tVCS the device is performing power
on reset operations.
During power-down or voltage drops below VCC Lockout maximum (VLKO), the VCC and VIO voltages must
drop below VCC Reset (VRST) minimum for a period of tPD for the part to initialize correctly when VCC and VIO
again rise to their operating ranges. See Figure 9.2 on page 72. If during a voltage drop the VCC stays above
VLKO maximum the part will stay initialized and will work correctly when VCC is again above VCC minimum. If
the part locks up from improper initialization, a hardware reset can be used to initialize the part correctly.
Normal precautions must be taken for supply decoupling to stabilize the VCC and VIO power supplies. Each
device in a system should have the VCC and VIO power supplies decoupled by a suitable capacitor close to
the package connections (this capacitor is generally on the order of 0.1 µF). At no time should VIO be greater
then 200 mV above VCC (VCC ≥ VIO - 200 mV).

10.3 Power-On Reset (POR) and Warm Reset
Normal precautions must be taken for supply decoupling to stabilize the VCC and VIO power supplies. Each
device in a system should have the VCC and VIO power supplies decoupled by a suitable capacitor close to
the package connections (this capacitor is generally on the order of 0.1 µF).
Notes:
1. Not 100% tested.
2. Timing measured from VCC reaching VCC minimum and VIO reaching VIO minimum to VIH on Reset and VIL on CE#.
3. RESET# Low is optional during POR. If RESET is asserted during POR, the later of tRPH, tVIOS, or tVCS will determine when CE# may go
Low. If RESET# remains Low after tVIOS, or tVCS is satisfied, tRPH is measured from the end of tVIOS, or tVCS. RESET must also be High
tRH before CE# goes Low.
4. VCC
≥
VIO - 200 mV during power-up.
5. VCC and VIO ramp rate can be non-linear.
6. Sum of tRP and tRH must be equal to or greater than tRPH.
10.3.1 Power-On (Cold) Reset (POR)
During the rise of power supplies the VIO supply voltage must remain less than or equal to the VCC supply
voltage. VIH also must remain less than or equal to the VIO supply.
The Cold Reset Embedded Algorithm requires a relatively long, hundreds of µs, period (tVCS) to load all of the
EAC algorithms and default state from non-volatile memory. During the Cold Reset period all control signals
including CE# and RESET# are ignored. If CE# is Low during tVCS the device may draw higher than normal
POR current during tVCS but the level of CE# will not affect the Cold Reset EA. CE# or OE# must transition
from High to Low after tVCS for a valid read or write operation. RESET# may be High or Low during tVCS. If
RESET# is Low during tVCS it may remain Low at the end of tVCS to hold the device in the Hardware Reset
state. If RESET# is High at the end of tVCS the device will go to the Standby state.
When power is first applied, with supply voltage below VRST then rising to reach operating range minimum,
internal device configuration and warm reset activities are initiated. CE# is ignored for the duration of the POR
operation (tVCS or tVIOS). RESET# Low during this POR period is optional. If RESET# is driven Low during
POR it must satisfy the Hardware Reset parameters tRP and tRPH. In which case the Reset operations will be
completed at the later of tVCS or tVIOS or tRPH.
During Cold Reset the device will draw ICC7 current.

10.3.2 Hardware (Warm) Reset
During Hardware Reset (tRPH) the device will draw ICC5 current.
When RESET# continues to be held at VSS, the device draws CMOS standby current (ICC4). If RESET# is
held at VIL, but not at VSS, the standby current is greater.
If a Cold Reset has not been completed by the device when RESET# is asserted Low after tVCS, the Cold
Reset# EA will be performed instead of the Warm RESET#, requiring tVCS time to complete.
See Figure 10.4, Hardware Reset on page 79.
After the device has completed POR and entered the Standby state, any later transition to the Hardware
Reset state will initiate the Warm Reset Embedded Algorithm. A Warm Reset is much shorter than a Cold
Reset, taking tens of µs (tRPH) to complete. During the Warm Reset EA, any in progress Embedded Algorithm
is stopped and the EAC is returned to its POR state without reloading EAC algorithms from non-volatile
memory. After the Warm Reset EA completes, the interface will remain in the Hardware Reset state if
RESET# remains Low. When RESET# returns High the interface will transit to the Standby state. If RESET#
is High at the end of the Warm Reset EA, the interface will directly transit to the Standby state.
If POR has not been properly completed by the end of tVCS, a later transition to the Hardware Reset state will
cause a transition to the Power-on Reset interface state and initiate the Cold Reset Embedded Algorithm.
This ensures the device can complete a Cold Reset even if some aspect of the system Power-On voltage
ramp-up causes the POR to not initiate or complete correctly. The RY/BY# pin is Low during cold or warm
reset as an indication that the device is busy performing reset operations.
Hardware Reset is initiated by the RESET# signal going to VIL.
