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 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. ODT Input 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, 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. 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 PRECHARGE 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 commands. DQ Input/Output Data input / output : Bi-directional data bus 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) control bit enables or disables all complementary data strobe signals.

Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. Storage Temperature is the case surface temperature on the denter/top side of the DRAM. For the measurement conditions. Please refer to JESD51-2 standard. 2.2 Operating Temperature Condition Symbol Toper Parameter Operating Temperature Rating Units Notes 0 to 85 °C 1,2 1. Operating Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2 standard. 2. The operatin temperature range are the temperature where all DRAM specification will be supported. Outside of this temperature rang, even it is still within the limit of stress condition, some deviation on portion of operation specification may be required. During operation, the DRAM case temperature must be maintained between 0 ~ 85°C under all other specification parameters. However, in some applications, it is desirable to operate the DRAM up to 95°C case temperature. Therefore 2 spec options may exist. 1) Supporting 0 - 85°C with full JEDEC AC & DC specifications. This is the minimum requirements for all oprating temperature options. 2) Supporting 0 - 85°C and being able to extend to 95°C with doubling auto-refresh commands in frequency to a 32 ms period(tRFI=3.9us). Note; Currently the periodic Self-Refresh interval is hard coded within the DRAM to a specificic value. There is a migration plan to support higher temperature Self-Refresh entry via the control of EMRS(2) bit A7. However, since Self-Refresh control function is a migrated process. For our DDR2 module user, it is imperative to check SPD Byte 49 Bit 0 to ensure the DRAM parts support higer than 85°C case temperature Self-Refresh entry. 1) if SPD Byte 49 Bit 0 is a “0” means DRAM does not support Self-Refresh at higher than 85°C, then system have to ensure the DRAM is at or below 85°C case temperature before initiating Self-Refresh operation. 2) if SPD Byte 49 Bit 0 is a “1” means DRAM supports Self-Refresh at higher than 85°C case temperature, then system can use register bit A7 at EMRS(2) control DRAM to operate at proper Self-Refresh rate for higher temperature. Please also refer to EMRS(2) register definition section and DDR2 DIMM SPD definition for details. Rev. 1.0 / Feb. 2005 10 1HY5PS12421(L)F HY5PS12821(L)F HY5PS121621(L)F 3.

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 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 (250mV to -500 mV for falling egdes). CK - CK = +500 mV 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). VDDQ DUT DQ DQS DQS RDQS RDQS Output Timing reference point VTT = VDDQ/2 25Ω 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. 3. DDR2 SDRAM output slew rate test load Output slew rate is characterized under the test conditions as shown below. VDDQ DUT DQ DQS, DQS RDQS, RDQS Output Test point VTT = VDDQ/2 25Ω Slew Rate Test Load 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 Rev. 1.0 / Feb. 2005 24 1HY5PS12421(L)F HY5PS12821(L)F HY5PS121621(L)F 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. tDQSH DQS DQS/ DQS tDQSL DQS tWPRE tWPST VIH(dc) VIH(ac) DQ D D VIL(ac) VIL(dc) tDS VIH(ac) tDS DM D D DMin DMin tDH DMin tDH VIH(dc) DMin VIL(ac) VIL(dc) Figure -- Data input (write) timing tCH tCL CK CK/CK CK DQS DQS/DQS DQS tRPRE tRPST DQ Q Q tDQSQmax Q Q tDQSQmax tQH tQH Figure -- Data output (read) timing 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.

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.

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 Rev. 1.0 / Feb. 2005 26 1HY5PS12421(L)F HY5PS12821(L)F HY5PS121621(L)F 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.

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. t DAL = (nWR) + ( tRP/tCK): For each of the terms above, if not already an integer, round to the next highest integer. tCK refers to the application clock period. nWR refers to the t WR parameter stored in the MRS. 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 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 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 different voltages. The actual voltage measurement points are not critical as long as the calculation is consistent.
