Pin Descriptions
The pin description table below is a comprehensive list of all possible pins for all DDR2
modules. All pins listed may not be supported on this module. See Pin Assignments for
information specific to this module.
Table 7: Pin Descriptions
Symbol Type Description
Ax Input Address inputs: Provide the row address for ACTIVE commands, and the column ad-
dress and auto precharge bit (A10) for READ/WRITE commands, to select one location
out of the memory array in the respective bank. A10 sampled during a PRECHARGE
command determines whether the PRECHARGE applies to one bank (A10 LOW, bank
selected by BAx) or all banks (A10 HIGH). The address inputs also provide the op-code
during a LOAD MODE command. See the Pin Assignments Table for density-specific
addressing information.
BAx Input Bank address inputs: Define the device bank to which an ACTIVE, READ, WRITE, or
PRECHARGE command is being applied. BA define which mode register (MR0, MR1,
MR2, and MR3) is loaded during the LOAD MODE command.
CKx,
CK#x
Input Clock: Differential clock inputs. All control, command, and address input signals are
sampled on the crossing of the positive edge of CK and the negative edge of CK#.
CKEx Input Clock enable: Enables (registered HIGH) and disables (registered LOW) internal circui-
try and clocks on the DDR2 SDRAM.
DMx Input Data mask (x8 devices only): DM is an input mask signal for write data. Input data
is masked when DM is sampled HIGH, along with that input data, during a write ac-
cess. Although DM pins are input-only, DM loading is designed to match that of the
DQ and DQS pins.
ODTx Input On-die termination: Enables (registered HIGH) and disables (registered LOW) termi-
nation resistance internal to the DDR2 SDRAM. When enabled in normal operation,
ODT is only applied to the following pins: DQ, DQS, DQS#, DM, and CB. The ODT input
will be ignored if disabled via the LOAD MODE command.
Par_In Input Parity input: Parity bit for Ax, RAS#, CAS#, and WE#.
RAS#, CAS#, WE# Input Command inputs: RAS#, CAS#, and WE# (along with S#) define the command being
entered.
RESET# Input Reset: Asynchronously forces all registered outputs LOW when RESET# is LOW. This
signal can be used during power-up to ensure that CKE is LOW and DQ are High-Z.
S#x Input Chip select: Enables (registered LOW) and disables (registered HIGH) the command
decoder.
SAx Input Serial address inputs: Used to configure the SPD EEPROM address range on the I2C
bus.
SCL Input Serial clock for SPD EEPROM: Used to synchronize communication to and from the
SPD EEPROM on the I2C bus.
CBx I/O Check bits. Used for system error detection and correction.
DQx I/O Data input/output: Bidirectional data bus.
DQSx,
DQS#x
I/O Data strobe: Travels with the DQ and is used to capture DQ at the DRAM or the con-
troller. Output with read data; input with write data for source synchronous opera-
tion. DQS# is only used when differential data strobe mode is enabled via the LOAD
MODE command.

Symbol Type Description
SDA I/O Serial data: Used to transfer addresses and data into and out of the SPD EEPROM on
the I2C bus.
RDQSx,
RDQS#x
Output Redundant data strobe (x8 devices only): RDQS is enabled/disabled via the LOAD
MODE command to the extended mode register (EMR). When RDQS is enabled, RDQS
is output with read data only and is ignored during write data. When RDQS is disa-
bled, RDQS becomes data mask (see DMx). RDQS# is only used when RDQS is enabled
and differential data strobe mode is enabled.
Err_Out# Output
(open drain)
Parity error output: Parity error found on the command and address bus.
VDD/VDDQ Supply Power supply: 1.8V ±0.1V. The component VDD and VDDQ are connected to the mod-
ule VDD.
VDDSPD Supply SPD EEPROM power supply: 1.7–3.6V.
VREF Supply Reference voltage: VDD/2.
VSS Supply Ground.
NC No connect: These pins are not connected on the module.
NF No function: These pins are connected within the module, but provide no functional-
ity.
NU Not used: These pins are not used in specific module configurations/operations.
RFU Reserved for future use.

General Description
DDR2 SDRAM modules are high-speed, CMOS dynamic random access memory mod-
ules that use internally configured 4 or 8-bank DDR2 SDRAM devices. DDR2 SDRAM
modules use DDR architecture to achieve high-speed operation. DDR2 architecture is
essentially a 4n-prefetch architecture with an interface designed to transfer two data
words per clock cycle at the I/O pins. A single read or write access for the DDR2 SDRAM
module effectively consists of a single 4n-bit-wide, one-clock-cycle data transfer at the
internal DRAM core and eight corresponding n-bit-wide, one-half-clock-cycle data
transfers at the I/O pins.
DDR2 modules use two sets of differential signals: DQS, DQS# to capture data and CK
and CK# to capture commands, addresses, and control signals. Differential clocks and
data strobes ensure exceptional noise immunity for these signals and provide precise
crossing points to capture input signals. A bidirectional data strobe (DQS, DQS#) is
transmitted externally, along with data, for use in data capture at the receiver. DQS is a
strobe transmitted by the DDR2 SDRAM device during READs and by the memory con-
troller during WRITEs. DQS is edge-aligned with data for READs and center-aligned
with data for WRITEs.
DDR2 SDRAM modules operate from a differential clock (CK and CK#); the crossing of
CK going HIGH and CK# going LOW will be referred to as the positive edge of CK. Com-
mands (address and control signals) are registered at every positive edge of CK. Input
data is registered on both edges of DQS, and output data is referenced to both edges of
DQS, as well as to both edges of CK.
Serial Presence-Detect EEPROM Operation
DDR2 SDRAM modules incorporate serial presence-detect. The SPD data is stored in a
256-byte EEPROM. The first 128 bytes are programmed by Micron to identify the mod-
ule type and various SDRAM organizations and timing parameters. The remaining 128
bytes of storage are available for use by the customer. System READ/WRITE operations
between the master (system logic) and the slave EEPROM device occur via a standard
I2C bus using the DIMM’s SCL (clock) SDA (data), and SA (address) pins. Write protect
(WP) is connected to VSS, permanently disabling hardware write protection.

Design Considerations
Simulations
Micron memory modules are designed to optimize signal integrity through carefully de-
signed terminations, controlled board impedances, routing topologies, trace length
matching, and decoupling. However, good signal integrity starts at the system level. Mi-
cron encourages designers to simulate the signal characteristics of the system's memo-
ry bus to ensure adequate signal integrity of the entire memory system.
Power
Operating voltages are specified at the DRAM, not at the edge connector of the module.
Designers must account for any system voltage drops at anticipated power levels to en-
sure the required supply voltage is maintained.

Start condition setup time tSU:STA 0.6 µs 3
Stop condition setup time tSU:STO 0.6 µs
WRITE cycle time tWRC 10 ms 4
Notes: 1. To avoid spurious start and stop conditions, a minimum delay is placed between SCL = 1
and the falling or rising edge of SDA.
2. This parameter is sampled.
3. For a restart condition or following a WRITE cycle.
4. The SPD EEPROM WRITE cycle time (tWRC) is the time from a valid stop condition of a
write sequence to the end of the EEPROM internal ERASE/PROGRAM cycle. During the
WRITE cycle, the EEPROM bus interface circuit is disabled, SDA remains HIGH due to
pull-up resistance, and the EEPROM does not respond to its slave address.
