1.3 PIN DESCRIPTION
PIN TYPE DESCRIPTION
CK, CK Input Clock: CK and CK are differential clock inputs. All address and control input signals are
sampled on the crossing of the positive edge of CK and negative edge of CK. Output
(read) data is referenced to the crossings of CK and CK (both directions of crossing).
CKE Input
Clock Enable: CKE HIGH activates, and CKE LOW deactivates internal clock signals, and
device input buffers and output drivers. Taking CKE LOW provides PRECHARGE POWER
DOWN and SELF REFRESH operation (all banks idle), or ACTIVE POWER DOWN (row
ACTIVE in any bank). CKE is synchronous for POWER DOWN entry and exit, and for
SELF REFRESH entry. CKE is asynchronous for SELF REFRESH exit. After VREF has
become stable during the power on and initialization sequence, it must be maintained
for proper 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 fers, excluding CK, CK and CKE ar e disabled 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 selection on systems with multiple banks. CS is considered part of the
command code.
ODT Input
On Die Termination Control : ODT(registered HIGH) enables on die termination resis-
tance internal to the DDR2 SDRAM. When enabled, ODT is only applied to DQ, DQS,
DQS, RDQS, RDQS, and DM signal f or x4 ,x8 con figur ations. For x16 configu r ation OD T
is applied to each DQ, UDQS/UDQS.LDQS/LDQS, UDM and LDM signal. The ODT pin
will be ignored if the Extended Mode R egister(EMRS(1)) is pr ogrammed to disable OD T.
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 loading. For x8 device, the function of DM or RDQS/ RDQS is
enabled by EMRS command.
BA0 - BA2 Input
Bank Address Inputs: BA0 - BA2 define to which bank an ACTIVE, Read, Write or PRE-
CHARGE command is being applied(For 256Mb and 512Mb, BA2 is not applied). Bank
address also determines if the mode register or extended mode register is to be
accessed during a MRS or EMRS cycle.
A0 -A15 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 respective bank. A10 is sampled during a precharge
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 MODE REGISTER SET com-
mands.

Data Strobe : Output with read data, input with write data. Edge aligned with read data,
centered in write data. For the x16, LDQS correspond to the data on DQ0~DQ7; UDQS
corresponds to the data on DQ8~DQ15. For the x8, an RDQS option using DM pin can
be enabled via the EMRS(1) to simplify read timing. The data strobes DQS, LDQS,
UDQS, and RDQS may be used in single ended mode or paired with optional comple-
mentary signals DQS, LDQS,UDQS and RDQS to provide diff erential pair signaling to the
system during both reads and wirtes. An EMRS(1) control bit enables or disables all
complementary data strobe signals.

of DDR2 for the Full Strength Default Driver Characteristics.
2. Impedance measur ement condition for output source dc current: VDDQ=1. 7V ; VOUT=1420mV ; (VOUT -VD DQ)/Ioh
must be less than 23.4 ohms for values of VOUT between VDDQ and VDDQ-280mV. Impedance measurement

3. Mismatch is absolute value between pull-up and pull-dn, both are measured at same temperature and voltage.
4. Slew rate measured from vil(ac) to vih(ac).
5. The absolute value of the slew rate as measured from DC to DC is equal to or greater than the slew rate as
measured from AC to AC. This is guaranteed by design and characterization.
6. This represents the step size when the OCD is near 18 ohms at nominal conditions across all process corners/
variations and represents only the DRAM uncertainty. A 0 ohm value(no calibration) can only be achieved if the

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 differen-
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.
5. AC timings are for linear signal transitions. See System Derating for other signal transitions.
6. These parameters guarantee device behavior, but they are not necessarily tested on each device.
They may be guaranteed by device design or tester correlation.
7. All voltages referenced to VSS.
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.

Specific Notes for dedicate d 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 satisfied.
4. A minimum of two clocks (2 * tCK) is required irrespective of operating frequency
5. Timings are guaranteed with command/address input slew rate of 1.0 V/ns. See System Derating for other slew rate
values.
6. Timings are guaranteed with data, mask, and (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 guaranteed with CK/CK differential slew rate of 2.0 V/ns. Timings are guaranteed for DQS signals with a
differen tial slew rate of 2.0 V/ns in differential strobe mode and a slew r ate of 1V/ns in single ended mode. See Syst em
Derating for other slew rate values.
8. tDS and tDH derating table (for DDR2- 400 / 533)
1) For all input signals the total tDS(setup time) and tDH(hold time) required is calculated by adding the datasheet value
to the derating value listed in above Table.
Setup(tDS) nominal slew rate for a rising signal is defined as the slew rate b etween the last crossing of VREF(dc) and the
first crossing of Vih(ac)min. Setup(tDS) nominal slew rate 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
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 ra te 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) no minal slew rate for a rising sign al is defined as the slew rate rate between the last crossing of Vil(dc) max and
the first crossing of VREF(dc). Hold (tDH) nominal slew rate for a falling signal is defined as the slew rate between the last
crossing of Vih(dc) min and the first crossing of VREF(dc). 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 slow slew 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 rate in between the values listed in table x, the derating valued may obtained by linear interpolation.
These values are typically not subject to production test. They are verified by design and characterization.

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 r ate for a falling signal is de fined as the slew rate betwee n 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 falling signal is defined as the slew rate between the last cross-
ing of VREF(dc). If the actual signal signal is always 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 any-
where 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 slow rates the total setup time might be negative(i.e. a v alid input signal will not ha ve reached V IH/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 interpolation.
These values are typically not subject to production test. They are verified by design and characterization.
10. The maximum limit for this parameter is not a device limit. The device will operate with a greater value for 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). F or 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 (tJIT(crosstalk)) into the clock traces.
12. t QH = t HP – t QHS, where: tHP = minimum half clock period for any given cycle 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 sk ew and output patt ern eff ects, and p-channel to n- channel va riation of the ou tput drivers
as well as output slew rate mismatch between DQS/ DQS and associated DQ in a ny given cycle.
14. DAL = WR + RU{tRP(ns)/tCK(ns)}, where RU stands for round up. WR ref e rs to the tWR parameter stored in the MRS.
For tRP, if the result of the division is not already an integer, round up to the next highest integer. tCK refers to the
application clock period.
Example: For DDR533 at tCK = 3.75ns with tWR programmed to 4 clocks.
tDAL = 4 + (15ns/3.75ns) clocks = 4+(4) clocks = 8 clocks.
15. 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 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 access time as valid data transitions. Thesed parameters ar e re fer enced
to a specific vo ltage le ve l which sp ecifies 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 diffe rent voltages. The actual voltage measurement points a re not critical as long as
the calculation is consistenet.
19. tRPST end point and tRPRE begin point are not referenced to a specific voltage level but specify when the device
output is no longer driving (tRPST), or begins driving (tRPRE). Below figure shows a method to calculate these
points when the device is no longer driving (tRPST), or begins driving (tRPRE). Below Figure shows a method to
calculate these points when the device is no longer driving (tRPST), or begins driving (tRPRE) by measuring the
signal at two different v oltages. The actual voltage meas urement points are not critical as long as the calculation is
consistent.
20. Input waveform timing with differential data strobe enabled MR[bit10] =0, is referenced from the input signal
crossing at the VIH(ac) level to the differential data strobe crosspoint for a rising signal, and from the input signal
crossing at the VIL(ac) level to the diff erential data strobe cr osspoint for a f alling signal applied to the device under
test.
21. Input waveform timing with differential data strobe enabled MR[bit10]=0, is referenced from the input signal
crossing at the VIH(dc) level to the differential data strobe crosspoint for a rising signal and VIL(dc) to the
differential data strobe crosspoint for a falling signal applied to the device under test.
22. Input waveform timing is referenced from the input signal crossing at the VIH(ac) level for a rising signal and VIL(ac) for a falling
signal applied to the device under test.
23. Input waveform timing is referenced from the input signal crossing at the VIL(dc) level for a rising signal and VIH(dc) for a falling
signal applied to the device under test.

24. tWTR is at least two clocks (2*tCK) independent of operation frequency.
25. Input waveform timing with single-ended data strobe enabled MR[bit10] = 1, is referenced from the input signal
crossing at the VIH(ac) level to the single-ended data strobe crossing VIH/L(dc) at the start of its transition for a
rising signal, and from the input signal crossing at the VIL(ac) level to the single-ended data strobe crossing
VIH/L(dc) at the start of its transition for a falling signal applied to the device under test. The DQS signal must be
monotonic between VIL(dc)max and VIH(dc) min.
26. Input waveform timing with single-ended data strobe enabled MR[bit10] = 1, is referenced from the input signal
crossing at the VIH(dc) level to the single-ended data strobe crossing VIH/L(ac) at the end of its transition for a
rising signal, and from the input signal crossing at the VIL(dc) level to the single-ended data strobe crossing
VIH/L(ac) at the end of its transition for a falling signal applied to the device under test. The DQS signal must be
monotonic between VIL(dc) max and VIH(dc) min.
27 . tCKE min of 3 clocks means CKE must be registered on three consecutive positiv e 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 transition,
CKE may not transition from its valid level during the time period of tIS + 2*tCK + tIH.
