1.3 PIN DESCRIPTION
PIN
TYPE
CK, CK
Input
DESCRIPTION
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).
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 asyn-
CKE
Input
chronous 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 buffers, excluding CK, CK and CKE are 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.
On Die Termination Control : ODT(registered HIGH) enables on die termination resistance internal to the DDR2 SDRAM. When enabled, ODT is only applied to DQ, DQS, DQS, RDQS, RDQS,
ODT
Input
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(EMRS(1)) is programmed to disable ODT.
RAS, CAS, WE
Input
Command Inputs: RAS, CAS and WE (along with CS) define the command being entered.
Input Data Mask : DM is an input mask signal for write data. Input Data is masked when DM is
DM
(LDM, UDM)
Input
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.
Bank Address Inputs: BA0 - BA2 define to which bank an ACTIVE, Read, Write or PRECHARGE
BA0 - BA2
Input
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.
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
A0 -A15
Input
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 commands.

DESCRIPTION
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 complementary signals DQS, LDQS,UDQS and RDQS
to provide differential pair signaling to the system during both reads and wirtes. An EMRS(1)

2. IDD specifications are tested after the device is properly initialized
3. Input slew rate is specified by AC Parametric Test Condition
4. IDD parameters are specified with ODT disabled.
5. Data bus consists of DQ, DM, DQS, DQS, RDQS, RDQS, LDQS, LDQS, UDQS, and UDQS. IDD values must be met with all
combinations of EMRS bits 10 and 11.
6. Definitions for IDD
LOW is defined as Vin ≤ VILAC(max)
HIGH is defined as Vin ≥ VIHAC(min)
STABLE is defined as inputs stable at a HIGH or LOW level
FLOATING is defined as inputs at VREF = VDDQ/2
SWITCHING is defined as: inputs changing between HIGH and LOW every other clock cycle (once per two clocks) for
address and control signals, and inputs changing between HIGH and LOW every other data transfer (once per clock) for DQ
signals not including masks or strobes.

General notes, which may apply for all AC parameters
1. Slew Rate Measurement Levels
a. Output slew rate for falling and rising edges is measured between 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 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 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 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).

AC Timing Reference Load
The output timing reference voltage level for single ended signals is the crosspoint with VTT. The output timing reference voltage
level for differential signals is the crosspoint of the true (e.g. DQS) and the complement (e.g. DQS) signal.

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 complement, DQS. This
distinction in timing methods is guaranteed by design and characterization. Note that when differential data strobe mode is disabled
via the EMRS, the complementary pin, DQS, must be tied externally to VSS through a 20 ohm to 10 K ohm resistor to insure proper
operation.

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
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 rate of 1V/ns in single ended mode. See System

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 between 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 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 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 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 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 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 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 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 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). 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 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 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. DAL = WR + RU{tRP(ns)/tCK(ns)}, where RU stands for round up. WR refers 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 are referenced to a
specific voltage level which specifies when the device output is no longer driving(tHZ), or begins driving (tLZ). Below figure
Rev. 0.4 / Sep. 2006
31

1HY5PS561621A(L)FP
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 measurement points are 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 voltages. The actual voltage
measurement 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 differential data strobe crosspoint for a falling 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

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 positive clock edges. CKE must remain at the valid input
