1.3 PIN DESCRIPTION
PIN TYPE DESCRIPTION
CK, CK Input Clock: CK and CK are differential clock inputs. All addres s and control input signals are sampled
on the crossing of the positive edge of CK and negative edge of CK. Output (read) data is refer-
enced to the crossin g s of CK and CK (both directions of crossi ng ).
CKE Input
Clock Enable: CKE HIGH activates, and CKE LOW deactiva tes internal clock signals , and device
input buffe rs and output drivers . Taking CKE L OW provides PRECHARGE POWER DOWN and SELF
REFRESH operation (all banks idl e), or ACTIVE PO WER DOWN (row ACTIVE in any bank). CKE is
synchronous for POWER DOWN entry and exit, and for SELF REFRESH entry. CKE is asynchro-
nous for SELF REFRESH exit. After VREF has become st able during the power on and initializat ion
sequence, it must be maintained f or pr oper operation of the CKE receiver. For proper self-refresh
entry and exit, VREF must be maintained to this input. CKE must be maintained HIGH throughout
READ and WRITE accesses . Input buf f ers, excluding CK, CK and CKE are disabl ed during POWER
DOWN. Input buffers, excluding CKE are disabled during SELF REFRESH.
CS Input Chip Select: All commands are masked when CS is registered HIGH. CS provides for external
bank select ion on systems with multiple banks. CS is co nsidered part of the comm a nd code.
ODT Input
On Die Termination Control: ODT (registered HIGH) enables on die termination re sistance
internal to the DDR2 SDRAM. When enabled, ODT is only applied to DQ, DQS, DQS, RD QS,
RDQS, and DM signal for x4,x8 configurations. For x16 configuration ODT is applied to each DQ,
UDQS/UDQS.LDQS/LDQS, UDM and LDM signal. The ODT pin will be ignored if the Extended
Mode Register(EMR(1)) is programmed to disable ODT.
RAS, CAS, WE Input Command Inputs: RAS, CAS and WE (along with CS) define the command being entered.
DM
(LDM, UDM) Input
Input Data Mask: DM is an input mask signal for write data. Input Data is masked when DM is
sampled High coincident with that input data during a WRITE access. DM is sampled on both
edges of DQS, Although DM pins are input only, the DM loading matches the DQ and DQS load-
ing. For x8 device, the function of DM or RDQS/ RDQ S is enabled by EMR command to EMR(1).
BA0 - BA2 Input
Bank Address Inputs: BA0 - BA2 define to which bank an ACTIVE, Read, W rite or PRE CHARGE
command is being applied (For 256Mb and 512Mb, BA2 is not applied). Bank address also deter-
mines if one of the mode register or extended mode register is to be accessed during a M R or
EMR command cycle.
A0 -Amax Input
Address Inputs: Provide the row address for ACTIVE commands, and the column address and
AUTO PRECHARGE bit for READ/WRITE commands to select one location out of the memory
array in the r espectiv e bank. A10 is sampled during a prechar ge command to determine whether
the PRECHARGE applies to one bank (A10 LOW) or all banks (A10 HIGH). If only one bank is to
be precharged, the bank is selected by BA0-BA2. The address inputs also provide the op code
during MRS or EMRS commands.
DQ Input/Output Data input / output: Bi-directional da ta bus
DQS, (DQS)
(UDQS),(UDQS)
(LDQS),(LDQS)
(RDQS),(RDQS)
Input/Output
Data Strobe: Output with read data, input with write data. Edge aligned with read data, cen-
tered in write data. For the x16, LDQS correspond to the data o n D Q0~DQ 7; UDQS co rresponds
to the data on DQ8~DQ15. For the x8, an RDQS option using DM pin can be enabled via the
EMR(1) to simplify read timing. The data strobes DQS, LDQS, UDQS, and RDQS may be used in
single ended mode or paired with optional complementary signals DQS, LDQS,UDQS and RDQS
to provide differential pair signaling to the system during both reads and writes. An EMR(1) con-
trol bit enables or disables all complementary data strobe signals.
In this data sheet, "differential DQS signals" refers to any of the following with A10 = 0 of EMR(1)

General notes, which may apply for all AC parameters
1. DDR2 SDRAM AC timing reference load
The following figure represents the timing reference load used in defining the relevant timing parameters
of the part. It is not intended to be either a precise representation of the typical system environment nor a
depiction of the actual load presented by a production tester. System designers will use IBIS or other simula-
tion tools to correlate the timing refer ence load to a system environment. Manuf acturers will correlate to their
production test conditions (generally a coaxial transmission line terminated at the tester ele ctronics).
The output timing reference voltage level for single ended signals is the crosspoint with VTT. The output tim-
ing reference voltage level for dif ferential signals is the crosspoint of the true (e.g. DQS) and the complement
(e.g. DQS) signal.
2. Slew Rate Measurement Levels
a. Output slew rate for f alling and rising edges is measured bet ween VTT - 250 mV and VTT + 250 mV for
single ended signals. For differential signals (e.g. DQS - DQS) output slew rate is measured between
DQS - DQS = -500 mV and DQS - DQS = +500mV. Output slew rate is guaranteed by design, but is
not necessarily tested on each device.
b. Input slew rate for single ended signals is measured from dc-level to ac-level: from VREF - 125 mV to
VREF + 250 mV for rising edges and from VREF + 125 mV and VREF - 250 mV for falling edges.
For differential signals (e.g. CK - CK) slew rate for rising edges is measured from CK - CK = -250 mV
to CK - CK = +500 mV (+250mV to -500 mV for falling edges).
c. VID is the magnitude of the differ ence between the input v oltage on CK and the input v oltage on CK, or
between DQS and DQS for differential strobe.

Output slew rate is characterized under the test conditions as shown below.

4. Differential data strobe
DDR2 SDRAM pin timings are specified for either single ended mode or differential mode depending on the
setting of the EMR “Enable DQS” mode bit; timing advantages of differential mode are realized in system
design. The method by which the DDR2 SDRAM pin timings are measured is mode dependent. In single
ended mode, timing relationships are measured re lative to the rising or falling edges of DQS crossing at VREF.
In differential mode, these timing relationships are measured relative to the crosspoint of DQS and its com-
plement, DQS. This distinction in timing methods is guaranteed by design and characterization. Note that
when differential data str obe mode is disabled via the EMR, the complementary pin, DQS, must be tied exter-
nally to VSS through a 20 Ω to 10 KΩ resistor to insure proper operation.
5. AC timings are for linear signal transitions. See System Derating for other signal transitions.
6. All voltages referenced to VSS.
7. These parameters guarantee device behavior, but they are not necessarily tested on each device. They
may be guaranteed by device design or tester correlation.
8. Tests for AC timing, IDD, and electrical (AC and DC) characteristics, may be conducted at nominal refer-
ence/supply voltage levels, but the related specifications and device operation are guaranteed for the full
voltage range specified.

Specific Notes for dedicated AC parameters
1. User can choose which active power down exit timing to use via MRS(bit 12). tXARD is expected to be
used for fast active power down exit timing. tXARDS is expected to be used for slow active power down exit
timing where a lower power value is defined by each vendor data sheet.
2. AL = Additive Latency
3. This is a minimum requirement. Minimum read to precharge timing is AL + BL/2 providing the tRTP and
tRAS(min) have been sa tisfied.
4. A minimum of two clocks (2 * tCK or 2 * nCK) is required irrespective of operating frequency
5. Timings are specified with command/address input slew rate of 1.0 V/ns. See System Derating for other
slew rate values.
6. Timings are guaranteed with DQs, DM, and DQS’s(DQS/RDQS in singled ended mode) input slew rate of
1.0 V/ns. See System Derating for other slew rate values.
7. Timings are specified with CK/CK differential s lew rat e of 2.0 V/ns. Timings ar e guara nteed for DQS si gnals
with a differential slew rate of 2.0 V/ns in differential strobe mode and a slew rate of 1V/ns in single ended
mode. See System Derating for other slew rate values.

1) For all input signals the total tDS(setup time) and tDH(hold time) required is calculated by adding the datasheet value to the der ating
value listed in Table x.
Setup(tDS) nominal slew rate for a rising sign al is defined as the slew rate between the last crossing of VREF(dc) and the first crossing
of Vih(ac)min. Setup(tDS) nominal slew rate f or a fallin g signal is defined as the slew rate between the last crossing of VREF(dc) and the
first crossing of Vil(ac)max. If the actual signal is always earlier than the nominal slew rate line between shaded ‘ VREF(dc) to ac reg ion ’,
use nominal slew rate for derating value(see Fig a.) If the actual signal is later t han the nominal slew rate line anyw here between shaded
‘VREF(dc) to ac region’, the slew rate of a tangent line to the actual signal from the ac level to dc level is used for derating value(see Fig b.)
Hold(tDH) nominal slew rate for a rising signal is defi ned as the slew rate between the last crossing of Vil(dc) max and the first crossing

If the actual signal is earlier than the nominal slew rate line anywhere between shaded ‘dc to VREF(dc)
region’, the slew rate of a tangent line to the actual signal from the dc level to VREF(dc) level is used for
derating value(see Fig d.)
Although for s low rates the total setup time might be negative(i.e. a valid input signal will not have
reached VIH/IL(ac) at the time of the rising clock transition) a valid input signal is still required to complete

For slew rates in between the values listed in table, the derating values may obtained by linear interpola-

1) For all input signals the total tIS(setup time) and tIH(hold) time) required is calculated by adding the

Setup(tIS) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of

the slew rate between the last crossing of VREF(dc) and the first crossin g of VIL(ac)max. If the actual signal is
always earlier than the nominal slew rate for line between shaded ‘VREF(dc) to ac region’, use nominal slew
rate for derating value(see fig a.) If the actual signal is later than the nominal slew rate line anywhere
between shaded ‘VREF(dc) to ac region’, the slew rate of a tangent line to the actual signal from the ac level
to dc level is used for derating value(see Fig b.)
Hold(tIH) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of
VIL(dc)max and the first crossing of VREF(dc). Hold(tIH) nominal slew rate for a falling signal is defined as the
slew rate between the last crossing of VREF(dc). If the actual signal is alw ays later than the nominal slew r ate
line between shaded ‘dc to VREF(dc) region’, use nominal slew rate for derating value(see Fig.c) If the actual
signal is earlier than the nominal slew rate line anywhere between shaded ‘dc to VREF(dc) region’, the slew
rate of a tangent line to the actual si gnal from the dc leve l to VREF(dc) level is used for der ating value(see Fig
d.)
Although for sl ow rates the total setup time might be negative(i.e. a valid input signal will not have reached
VIH/IL(ac) at the time of the rising clock transition) a valid input signal is still required to comple te the transi-
tion and reach VIH/IL(ac).
For slew rates in between the values listed in table, the derating values may obtained by linear interpolation.

10. The maximum limit for this par a meter is not a device limit. The device will oper ate with a greater v alue f or
this parameter, but system performance (bus turnaround) will degrade accordingly.
11. MIN (t CL, t CH) refers to the smaller of the actual clock LOW time and the actual clock HIGH time as
provided to the device (i.e. this value can be greater than the minimum specification limits for t CL and t CH).
For example, t CL and t CH are = 50% of the period, less the half period jitter (t JIT(HP)) of the clock source,
and less the half period jitter due to crosstalk (t JIT(crosstalk)) into the clock traces.
12. t QH = t HP – t QHS, where:
tHP = minimum half clock period for any give n cy cle and is defined by clock HIGH or clock LOW (tCH, tCL).
tQHS accounts for:
1) The pulse duration distortion of on-chip clock circuits; and
2) The worst case push-out of DQS on one transition followed by the worst case pull-in of DQ on the
next transition, both of which are , separately, due to data pin skew and output pattern effects, and
p-channel to n-channel variation of the output drivers.
13. tDQSQ: Consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the
output drivers as well as output slew rate mismatch between DQS/ DQS and associated DQ in any given cycle.
14. t DAL = (nWR) + (tRP/tCK):
For each of the terms abov e, if not already an integer, round to the ne xt highest integer. tCK ref ers to the appli-
cation clock period. nWR refers to the t WR parameter stored in the MR.
Example: For DDR533 at t CK = 3.75 ns with t WR programmed to 4 clocks. tDAL = 4 + (15 ns / 3.75 ns)
clocks =4 +(4)clocks=8clocks.
15. The clock frequency is allowed to change during self–refresh mode or precharge power-down mode.
In case of clock frequency chan ge during prechar ge power -down, a specific procedur e is required as described
in section 2.9.
16. ODT turn on time min is when the device leaves high impedance and ODT resistance begins to turn on.
ODT turn on time max is when the ODT resistance is fully on. Both are measured from tAOND.
17. ODT turn off time min is when the device starts to turn off ODT resistance.
ODT turn off time max is when the bus is in high impedance. Both are measured from tAOFD.
18. tHZ and tLZ transitions occur in the same ac cess time as valid data transitions. These parameters are
referenced to a specific voltage level which specifies when the device output is no longer driving (tHZ), or
begins driving (tLZ). Below figure shows a method to calculate the point when device is no longer driving
(tHZ), or begins driving (tLZ) by measuring the signal at two different voltages. The actual voltage measure-
ment points are not critical as long as the calculation is consistent.

24. tWTR is at least two clocks (2 x tCK or 2 x nCK) independent of operation frequency.
25. Input waveform timing with single-ended data strobe enabled MR[bit10] = 1, is referenced from the

27. tCKE min of 3 clocks means CKE must be registered on three cons ecutive positive clock edges. CKE
must remain at the valid input level the entire time it takes to achieve the 3 clocks of registration. Thus,
after any CKE tr ansition, CKE may not tr ansition f rom its v alid leve l during the time period of tIS + 2 x tCK

28. If tDS or tDH is violated, data corruption may occur and the data must be re-written with valid data

29. These paramet ers are measur ed from a command/address signal (CKE, CS, RAS, CAS, WE, ODT, BA0,
A0, A1, etc.) transition edge to its respective clock signal (CK/CK) crossing. The spec values are not
affe cted by the amount of clock jit ter applied (i.e. t JIT (per), tJIT (cc), etc .), as the setup and hold are r el-

met whether clock jitter is present or not.
30. These paramete rs are measured fr om a data strobe signal ((L/U/R)DQS/DQS) cr ossing to its respective
clock signal (CK/CK) crossing. The spec values are not affected by the amount of clock jitter applied (i.e.
tJIT (per), tJIT (cc), etc.), as these are relative to the clock signal crossing. That is, these parameters
should be met whether clock jitter is present or not.
31. These parameters are measured from a data signal ((L/U) DM, (L/U) DQ0, (L/U) DQ1, etc.) transition
edge to its respective data strobe signal ((L/U/R)DQS/DQS) crossing.

are satisfied.
For example, the device will support tnRP = RU {tRP / tCK (avg)}, which is in clock cycles, if all input clock
jitter specifications are met. This means: For DDR2-667 5-5-5, of which tRP = 15ns, the device will support
tnRP =RU {tRP / tCK (avg)} = 5, i.e. as long as the input clock jitter specifications are met, Precharge
command at Tm and Active command at Tm+5 is valid ev en if (Tm+5 - Tm) is less than 15ns due to input
clock jitter.
33. tDAL [nCK] = WR [nCK] + tnRP [nCK] = WR + RU {tRP [ps] / tCK (avg) [ ps]}, wher e WR is the value
programmed in the mode register set.
34. New units, ‘tCK (avg)’ and ‘nCK’, are introduced in DDR2-667 and DDR2-800.
Unit ‘tCK (avg)’ represents the actual tCK (avg) of the input clock under operation.
Unit ‘nCK’, represents one clock cycle of the input clock, counting the actual clock edges.
Note that in DDR2-400 and DDR2-533, ‘tCK’, is used for both concepts.
ex) tXP = 2 [nCK] means; if Power Down exit is registered at Tm, an Active command may be registered
at Tm+2, even if (Tm+2 - Tm) is 2 x tCK (avg) + tERR(2per),min.

'input clock jitter spec par ameters' and these parameters apply to DDR2-667 and DDR2-800 only. The jitter

36. These parameters are specified per their average values, however it is understood that the following
relationship between the average timing and the absolute instantaneous timing holds at all times. (Min and
max of SPEC values are to be used for calculations in the table below.)
Example: For DDR2-667, tCH (abs), min = (0.48 x 3000 ps) - 125 ps = 1315 ps
37. tHP is the minimum of the absolute half period of the actual input cloc k. tHP is an input parameter but
not an input specification parameter. It is used in conjunction with tQHS to derive the DRAM output timing
tQH.
The value to be used for tQH calculation is determined by the following equation;
tHP = Min (tCH (abs), tCL (abs)),
where,
tCH (abs) is the minimum of the actual instantaneous clock HIGH time;
tCL (abs) is the minimum of the actual instantaneous clock LOW time;
38. tQHS accounts for:
1) The pulse duration distortion of on-chip clock circuits, which represents how well the actual tHP at the
input is transferred to the output; and
2) The worst case push-out of DQS on one transition followed by the worst case pull-in of DQ on the next
transition, both of which are independent of each other, due to data pin skew , output pattern effects, and
p-channel to n-channel variation of the output drivers
39. tQH = tHP ? tQHS, where:
tHP is the minimum of the absolute half period of the actual input clock; and
tQHS is the specification value under the max column.
{The less half-pulse width dist ortion present, the larg er the tQH v alue is; and the larger the valid data eye
will be.}
Examples:
1) If the system provides tHP of 1315 ps into a DDR2-667 SDRAM, the DRAM provides tQH of 975 ps min-
imum.
2) If the system provides tHP of 1420 ps into a DDR2-667 SDRAM, the DRAM provides tQH of 1080 ps
minimum.
40. When the device is operated with input clock jitter, this parameter needs to be derated by the actual
tERR(6-10per) of the input clock. (output deratings are relative to the SDRAM input clock .)
For example, if the measured jitter into a DDR2-667 SDRAM has tERR(6-10per),min = - 272 ps and
tERR(6-10per), max = + 293 ps, then tDQSCK, min (derated) = tDQSCK, min - tERR(6-10per),max = -
400 ps - 293 ps = - 693 ps and tDQSCK, max (derated) = tDQSCK, max - tERR(6-10per),min = 400 ps +

272 ps = + 672 ps. Similarly, tLZ (DQ) for DDR2-667 derates to tLZ (DQ), min (derated) = - 900 ps - 293
ps = - 1193 ps and tLZ (DQ), max (derated) = 450 ps + 272 ps = + 722 ps. (Caution on the min/max
usage!)
41. When the device is operated with input clock jitter, this parameter needs to be derated by the actual
tJIT (per) of the input clock. (output deratings are relative to the SDRAM input clock.)
For example, if the measured jitter into a DDR2-667 SDRAM has tJIT (per), min = - 72 ps and tJIT (per),
max = + 93 ps, th en tRPRE, min (derated) = tRPRE, min + tJIT (per), min = 0.9 x tCK (avg) - 72 ps = +

ps. (Caution on the min/max usage!)
42. When the device is operated with input clock jitter, this parameter needs to be derated by the actual
tJIT (duty) of the input clock. (output deratings are relative to the SDRAM input clock.)
For example, if the measured jitter into a DDR2-667 SDRAM has tJIT (duty), min = - 72 ps and tJIT (duty),
max = + 93 ps, then tRPST, min (derated) = tRP ST, min + tJIT (dut y), min = 0.4 x tCK ( a vg) - 72 ps = +
928 ps and tRPST, max (derated) = tRPST, max + tJIT (duty), max = 0.6 x tCK (avg) + 93 ps = + 1592 ps.
(Caution on the min/max usage!)
43. When the device is operated with input clock jitter, this parameter needs to be derated by {-
tJIT (duty), max - tERR(6-10per),max} and {- tJIT (duty), min - tERR(6-10per),min} of the actual input
clock.(ou tput deratings are relative to the SDR AM input clock.)
For example, if the measured jitter into a DDR2-667 SDRAM has tERR(6-10per),min = - 272 ps, tERR(6-
10per), max = + 293 ps, tJIT (duty), min = - 106 ps and tJIT (duty), max = + 94 ps, then tAOF, min (der-
ated) = tAOF, min + {- tJIT (dut y), max - tERR(6-10p er),max} = - 450 ps + {- 94 ps - 293 ps} = - 837 ps
and tAOF, max (derated) = tAOF, max + {- tJIT (duty), min - tERR(6-10per),min} = 1050 ps + {106 ps +
272 ps} = + 1428 ps. (Caution on the min/max usage!)
44. For tAOFD of DDR2-400/533, the 1/2 clock of tCK in the 2.5 x tCK assumes a tCH, input clock HIGH
pulse width of 0.5 relative to tCK. tAOF, min and tAOF, max should each be derated by the same amount
as the actual amount of tCH off set present at the DRAM input with re spect to 0.5. For example, if an input
clock has a worst case tCH of 0.45, the tAOF, min should be derated by subtracting 0.05 x tCK from it,
whereas if an input clock has a worst case tCH of 0.55, the tAOF, max should be derated by adding 0.05 x
tCK to it. Therefore, we have;
tAOF, min (derated) = tAC, min - [0.5 - Min(0.5, tCH, min)] x tCK
tAOF, max (derated) = tAC, max + 0.6 + [Max(0.5, tCH, max) - 0.5] x tCK
or
tAOF, min (derated) = Min (tAC, min, tAC, min - [0.5 - tCH, min] x tCK)
tAOF, max (derated) = 0.6 + Max (tAC, max, tAC, max + [tCH, max - 0.5] x tCK)
where tCH, min and tCH, max are the minimum and maximum of tCH actually measured at the DRAM
input balls.
45. Fo r tAOFD of DDR2-667/800, the 1/2 clock of nCK in the 2.5 x nCK assumes a tCH (avg), aver age input
clock HIGH pulse width of 0.5 relative to tCK (avg). tAOF, min and tAOF, max should each be derated by
the same amount a s t he act ual amo unt of tCH (a vg) of f s et pr esent at the DR AM input with r esp ect t o 0.5.

tracting 0.02 x tCK (avg) from it, whereas if an input clock has a worst case tCH (avg) of 0.52, the tAOF,
max should be derated by adding 0.02 x tCK (avg) to it. Therefore, we have;
tAOF, min (derated) = tAC, min - [0.5 - Min(0.5, tCH (avg), min)] x tCK (avg)
tAOF, max (derated) = tAC, max + 0.6 + [Max(0.5, tCH (avg), max) - 0.5] x tCK (avg)

tAOF, max (derated) = 0.6 + Max (tAC, max, tAC, max + [tCH (avg), ma x - 0.5] x tCK (avg))
where tCH (avg), min and tCH (avg), max are the minimum and maximum of t CH (avg) actually measur ed
at the DRAM input balls.
Note that these deratings are in addition to the tAOF derating per input clock jitter, i.e. tJIT (duty) and
tERR(6-10per). However tAC values used in the equations shown above are from the timing parameter
table and are not derated. Thus the final derated values for tAOF are;
tAOF, min (derated _ final) = tAOF, min (derated) + {- tJIT (duty), max - tERR(6-10per),max}
tAOF, max (derated _ final) = tAOF, max (derated) + {- tJIT (duty), min - tERR(6-10per),min}

General notes, which may apply for all AC parameters
1. Slew Rate Measurement Levels
a. Output slew ra te for fallin g and rising edges is meas ured between VT T - 250 mV and VTT + 250 mV for single ended
signals.
For differential signals (e.g. DQS - DQS) output slew rate is measured between DQS - DQS = -500 mV and DQS
- DQS = +500mV. Output slew rate is guaranteed by design, but is not necessarily tested on each device.
b. Input slew rate for single ended signals is measured from dc-level to ac-level: from VIL(dc) to VIH(ac) for
rising edges and from
VIH(dc) and VIL(ac) for falling edges.
For differential signals (e.g. CK - CK) slew rate for rising edges is measured from CK - CK = -250 mV to CK - CK =
+500 mV(250mV to -500 mV for falling egdes).
c. VID is the magnitude of the difference between the input voltage on CK and the input voltage on CK, or between
DQS and DQS for differential strobe.
2. DDR2 SDRAM AC timing reference load
The following figure represents the timing reference load used in defining the relevant timing parameters of the part.
It is not intended to be either a precise repr esentation of the typical sys tem en vironment nor a depiction of the actual
load presented by a production tester. System designers will use IBIS or other simulation tools to correlate the timing
reference load to a system environment. Manufacturers will correlate to their production test conditions (generally a
coaxial transmission line terminated at the tester electronics).
The output timing reference voltage level for single ended signals is the crosspoint with VTT. The output timing refer-
ence voltage level for differential signals is the crosspoint of the true (e.g. DQS) and the complement (e.g. DQS)
signal.
3. DDR2 SDRAM output slew rate test load
Output slew rate is characterized under the test conditions as shown below.
4. Differential data strobe
DDR2 SDRAM pin timings are specified for either single ended mode or differential mode depending on the setting of
the EMRS “Enable DQS” mode bit; timing advantages of differential mode are realized in system design. The method
by which the DDR2 SDRAM pin timings are measured is mode dependent. In single

VREF. In differential mode, these timing relationships are measured relative to the crosspoint of DQS and its comple-
ment, DQS. This distinction in timing methods is guaranteed by design and characterization. Note that when differe n-
tial data strobe mode is disabled via th e EMRS, the complementary pin, DQS, must be tied e xternally to VSS thr ough a
20 ohm to 10 K ohm resistor to insure proper operation.

7. These parameters guarantee device behavior, but they are not necessarily tested on each device.
They may be guaranteed by device design or tester correlation.
8. Tests for AC timing, IDD, and electrical (AC and DC) characteristics, may be conducted at nominal reference/
supply voltage levels, but the related specifications and device operation are guaranteed for the full voltage
range specified.

differen tial slew rate of 2.0 V/ns in differential strobe mode and a slew ra te of 1V/ns in single ended mode. See S ystem
Derating for other slew rate values.
1) For all input signals the total tIS(setup time) and tIH(hold) time) required is calculated by adding the
datasheet value to the derating value listed in above Table.
Setup(tIS) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of
VREF(dc) and the first crossing of VIH(ac)min. Setup(tIS) nominal slew ra te for a falling signal is defined as the
slew rate between the last crossing of VREF(dc) and the first crossing of VIL(ac)max. If the actual signal is
always earlier than the nominal slew rate for line between shaded ‘VREF(dc) to ac region’, use nominal slew
rate for derating value(see fig a.) If the actual signal is later than the nominal slew rate line anywhere
between shaded ‘VREF(dc) to ac region’, the slew rate of a tangent line to the actual signal from the ac level to
dc level is used for derating value(see Fig b.)
Hold(tIH) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of
VIL(dc)max and the first crossing of VREF(dc). Hold(tIH) nominal slew rate for a f alling signal is defined as the
slew rate be tween the last crossing of VREF(dc). If the actual signal is alw ays later than the nominal slew rate
line between shaded ‘dc to VREF(dc) region’, use nominal slew rate for derating value(see Fig.c)

If the actual signal is earlier than the nominal slew rate line anywhere between shaded ‘dc to VREF(dc)
region’, the slew rate of a tangent line to the actual signal from the dc level to VREF(dc) level is used for
derating value(see Fig d.)
Although for s low rates the total setup time might be negative(i.e. a valid input signal will not have
reached VIH/IL(ac) at the time of the rising clock transition) a valid input signal is still required to complete
the transition and reach VIH/IL(ac).
For slew rates in between the values listed in table, the derating values may obtained by linear interpola-
tion.
These values are typically not subject to production test. They are verified by design and characterization.

10. The maximum limit for this par ameter is not a device limit. The device will operate with a greater v alue
for this parameter, but system performance (bus turnaround) will degrade accordingly.
11. tDQSQ: Consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the output
drivers as well as output slew rate mismatch between DQS / DQS and associated DQ in any given cycle.
12. The clock frequency is allowed to change during self–refresh mode or precharge power-down mode. In case of
clock frequency change during precharge power-down, a specific procedure is required as described in section Input

13. ODT turn on time min is when the device leaves high impedance and ODT resistance begins to turn on. ODT turn
on time max is when the ODT resistance is fully on. Both are measured from tAOND, which is interpreted as 2 clock

14. OD T turn of f time min is when the device starts to turn off ODT resistance. ODT turn off time max is when the bus
is in high impedance. Both are measured from tAOFD, which is interpreted as 0.5 x tCK(avg) [ns] after the second
trailing clock edge counting from the clock edge that registered a first ODT LOW and by counting the actual input clock
edges. For DDR2-1066, this is 0.9375 [ns] (= 0.5 x 1.875 [ns]) after the second trailing clock edge counting from the
clock edge that registered a first ODT LOW and by counting the actual input clock edges.

24. These parameters are measured from a command/address signal (CKE, CS, RAS, CAS, WE, ODT, BA0, A0, A1,
etc.) transition edge to its respective clock signal (CK/CK) crossing. The spec v alues are not aff ected by the amount of
clock jitter applied (i.e. tJIT(per), tJIT(cc), etc.), as the setup and hold are relative to the clock signal crossing that
latches the command/address. That is, these parameters should be met whether clock jitter is present or not.
25. These paramete rs are measured from a data strobe si gnal ((L/U/R)DQS/DQS) crossing to its respective clock

26. These parameters are measured from a data signal ((L/U) DM, (L/U) DQ0, (L/U) DQ1, etc.) transition
edge to its respective data strobe signal ((L/U/R)DQS/DQS) crossing.
27. For these pa rameters, the DDR2 SDRAM device is characterized and verified to support
tnPARAM = RU{tPARAM / tCK(avg)}, which i s in c lock cy cles, assuming all input clock jitter specifications
are satisfied.
Fo r example, the device will support tnRP = RU {tRP / tCK(a vg)}, which is in c lock cycles, if all input clock
jitterspecifications are met. This means: For DDR2-1066 7-7-7, of which tRP = 13.125ns, the device will
support tnRP =RU{tRP / tCK(avg)} = 7, i.e. as long as the input clock jitter specifications are met, Pre-
charge command at Tm and Active command at Tm+7 is valid even if (Tm+7 - Tm) is less than 13.127ns
due to input clock jitter.
28. Specific Note 28 tDAL [nCK] = WR [nCK] + tnRP [nCK] = WR + RU {tRP [ps] / tCK(avg) [ps] }, where WR is the
value programmed in the mode register set and RU stands for round up.
Example: For DDR2-1066 7-7-7 at tCK(avg) = 1.875 ns with WR programmed to 8 nCK,
tDAL = 8 + RU {13.125 ns / 1.875 ns} [nCK] = 8 + 7 [nCK] = 15 [nCK]
29.New units, ‘tCK(avg)’ and ‘nCK’, are introduced in DDR2-1066.
Unit ‘tCK(avg)’ represents the actual tCK(avg) of the input clock under operation.
Unit ‘nCK’ represents one clock cycle of the input clock, counting the actual clock edges.
ex) tXP = 3 [nCK] means; if Power Down exit is registered at Tm, an Active command may be registered at Tm+3,
even if (Tm+3 - Tm) is 3 x tCK(avg) + tERR(3per),min.
30. Input c lock jitter spec parameter. These parameters and the ones in the table below are re ferred to as

32. tHP is the minimum of the absolute half period of the actual input clock. tHP is an input parameter but not an input
specification parameter. It is used in conjunction with tQHS to derive the DRAM output timing tQH.
The value to be used for tQH calculation is determined by the following equation;
tHP = Min ( tCH(abs), tCL(abs) ),
where,
tCH(abs) is the minimum of the actual instantaneous clock HIGH time;
tCL(abs) is the minimum of the actual instantaneous clock LOW time;

33. tQHS accounts for:
1) The pulse duration distortion of on-chip clock circuits, which represents how well the actual tHP at the
input is transferred to the output; and
2) The worst case pus h-out of DQS on one transition followed by t he w orst ca se pull- in o f DQ on the ne xt
transition, both of which are independent of each other, due to data pin skew, output pattern effects, and
p-channel to n-channel variation of the output drivers
34. tQH = tHP - tQHS, where:
tHP is the minimum of the absolute half period of the actual input clock; and
tQHS is the specification value under the max column.
{The less half -pulse widt h distortion present , the larger the tQH v alue is; and the larger the v alid data eye
will be.}
Examples:
1) If the system provides tHP of 1315 ps into a DDR2-1066 SDRAM, the DRAM provides tQH of 575 ps
minimum.
2) If the system provides tHP of 900 ps into a DDR2-1066 SDRAM, the DRAM provides tQH of 650 ps min-
imum.
35. When the device is operated with input clock jitter, this parameter needs to be derated by the actual
tERR(6-1 0per) of the input clock. (output deratings are relative to the SDRAM input clock.)
For example, if the measured jitter into a DDR2-1066 SDRAM has tERR(6-10per),min = - 202 ps and tERR(6-
10per),max = + 223 ps,
then tDQSCK,min(derated) = tDQSCK,min - tERR(6-10per),max = - 300 ps - 223 ps = - 523 ps and tDQSCK,max(der-
ated) = tDQSCK,max - tERR(6-10per),min = 300 ps + 202 ps = + 502 ps. Similarly, tLZ(DQ) for DDR2-1066 derates to
tLZ(DQ),min(derate d) = - 700 ps - 223 ps = - 923 ps and tLZ(DQ),max(derated) = 350 ps + 202 ps = + 552 ps. (Cau-
tion on the min/max usage!)
36. When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJIT(per) of
the input clock. (output deratings are relative to the SDRAM input clock.)
For example, if the measured jitter into a DDR2-1066 SDRAM has tJIT(per),min = - 72 ps and tJIT(per),max = + 63
ps, then tRPRE,min(derated) = tRPRE,min + tJIT(per),min = 0.9 x tCK(avg) - 72 ps = + 1615.5 ps and
tRPRE,max(der ated) = tRPRE,max + tJIT(per),max = 1.1 x tCK(avg) + 63 ps = + 2125.5 ps. (Caution on the min/max

37. When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJIT(duty) of

38 When the device is operated with input clock jitter, this parameter needs to be derated by { - tJIT(duty),max -

ative to the SDRAM input clock.)
For example, if the measured jitter into a DDR2-1066 SDRAM has tERR(6-10per),min = - 202 ps, tERR(6-10per),max
= + 223 ps, tJIT(duty),min = - 66 ps and tJIT(duty),max = + 74 ps, then tAOF,min(derated) = tAOF,min + { -
tJIT(duty),max - tERR(6-10per),max } = - 350 ps + { - 74 ps - 223 ps} = - 64 7 ps and tAOF,max(derated) = tAOF,max

39. For tAOFD of DDR2-1066, the 1/2 clock of nCK in the 2.5 x nCK assumes a tCH(avg), average input clock HIGH
pulse width of 0.5 relative to tCK(avg). tAOF,min and tAOF,max should each be derated by the same amount as the
actual amount of tCH(avg) offset present at the DRAM input with respect to 0.5. For example, if an input clock has a
worst case tCH(avg) of 0.48, the tAOF,min should be derated by subtracting 0.02 x tCK(avg) from it, whereas if an
input clock has a worst case tCH(avg) of 0.52, the tAOF,max should be derated by adding 0.02 x tCK(av g) to it. There-
fore, we have;
tAOF,min(derated) = tAC,min - [0.5 - Min(0.5, tCH(avg),min)] x tCK(avg)
tAOF,max(derated) = tAC,max + 0.6 + [Max(0.5, tCH(avg),max) - 0.5] x tCK(avg)
or
tAOF,min(derated) = Min(tAC,min, tAC,min - [0.5 - tCH(avg),min] x tCK(avg))
tAOF,max(derated) = 0.6 + Max(tAC,max, tAC,max + [tCH(avg),max - 0.5] x tCK(avg))
where tCH(avg),min and tCH(avg),max are the minimum and maximum of tCH(avg) actually measured at
the DRAM input balls.
Note that these deratings are in addition to the tAOF derating per input clock jitter, i.e. tJIT(duty) and tERR(6-10per).
However tAC values used in the equations shown above are from the timing parameter table and are not derated.
Thus the final derated values for
tAOF are;
tAOF,min(derated_final) = tAOF,min(derated) + { - tJIT(duty),max - tERR(6-10per),max }
tAOF,max(derated_final) = tAOF,max(derated) + { - tJIT(duty),min - tERR(6-10per),min }
