All address and command lines are sampled on the cross point of the rising edge of CK and falling edge of CK. A Delay Locked Loop (DLL) circuit is driven from the clock inputs and output timing for read operations is synchronized to the input clock. Activates the DDR3 SDRAM CK signal when high and deactivates the CK signal when low. By deactivating the clocks, CKE low initiates the Power Down mode or the Self Refresh mode. Enables the associated DDR3 SDRAM command decoder when low and disables the command decoder when high. When the command decoder is disabled, new commands are ignored but previous operations continue. Rank 0 is selected by S0; Rank 1 is selected by S1. Asserts on-die termination for DQ, DM, DQS, and DQS signals if enabled via the DDR3 SDRAM mode register. When sampled at the cross point of the rising edge of CK, signals CAS, RAS, and WE define the operation to be executed by the SDRAM. Reference voltage for SSTL15 inputs. IN Cross Point CKE[1:0] IN Active High S[1:0] IN Active Low ODT[1:0] RAS, CAS, WE VREFDQ VREFCA BA[2:0] IN IN Supply IN Active High Active Low — Selects which SDRAM internal bank of eight is activated. During a Bank Activate command cycle, defines the row address when sampled at the cross point of the rising edge of CK and falling edge of CK. During a Read of Write command cycle, defines the column address when sampled at the cross point of the rising edge of CK and falling edge of CK. In addition to the column address, AP is used to invoke autoprecharge operation at the end of the burst read or write cycle. If AP is high autoprecharge is selected and BA0-BAn defines the bank to be precharged. If AP is low, autoprecharge is disabled. During a Precharge command cycle, AP is used in conjunction with BA0-BAn to control which bank(s) to precharge. If AP is high, all banks will be precharged regardless of the state of BA0-BAn inputs. If AP is low, then BA0-BAn are used to define which bank to precharge. A12(BC) is samples during READ and WRITE commands to determine if burst chop (on-the-fly) will be performed (HIGH, no burst chop: LOW, burst chopped). Data Input/Output pins. The data write masks, associated with one data byte. In Write mode, DM operates as a byte mask by allowing input data to be written if it is low but blocks the write operation if it is high. In Read mode, DM lines have no effect. Power supplies for core, I/O, Serial Presence Detect, and ground for the module. A[9:0], A10/AP, A11, A12/BC A[15:13] IN — DQ[63:0] DM[7:0] VDD, VDDSPD VSS I/O IN — Active High Supply DQS[7:0], DQS[7:0] I/O The data strobes, associated with one data byte, sourced with data transfers. In Write mode, the data strobe is sourced by the controller and is centered in the data window. Cross Point In Read mode, the data strobe is sourced by the DDR3 SDRAMs and is sent at the leading edge of the data window. DQS signals are complements, and timing is relative to the crosspoint of respective DQS and DQS. — These signals are tied at the system planar to either VSS or VDDSPD to configure the serial SPD EEPROM address range. SA[1:0] IN Rev. 0.2 / Feb. 2010 6 Symbol SDA Type I/O Polarity — Function This bidirectional pin is used to transfer data into or out of the SPD EEPROM. A resistor must be connected from the SDA bus line to VDDSPD on the system planar to act as a pullup. This signal is used to clock data into and out of the SPD EEPROM. A resistor may be connected from the SCL bus time to VDDSPD on the system planar to act as a pullup. SCL IN OUT (open drain) Supply IN — EVENT This signal indicates that a thermal event has been detected in the thermal sensing device.The system should guarantee the electrical level requirement is met for the Active Low EVENT pin on TS/SPD part. No pull-up resister is provided on DIMM. Serial EEPROM positive power supply wired to a separate power pin at the connector which supports from 3.0 Volt to 3.6 Volt (nominal 3.3V) operation. The RESET pin is connected to the RESET pin on the register and to the RESET pin on the DRAM.

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 center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2 standard. 3. VDD and VDDQ must be within 300mV of each other at all times; and VREF must not be greater than 0.6XVDDQ,When VDD and VDDQ are less than 500mV; VREF may be equal to or less than 300mV. DRAM Component Operating Temperature Range Temperature Range Symbol TOPER Notes: 1. Operating Temperature TOPER is the case surface temperature on the center / top side of the DRAM. For measurement conditions, please refer to the JEDEC document JESD51-2. 2. The Normal Temperature Range specifies the temperatures where all DRAM specifications will be supported. During operation, the DRAM case temperature must be maintained between 0 - 85oC under all operating conditions. 3. Some applications require operation of the DRAM in the Extended Temperature Range between 85oC and 95oC case temperature. Full specifications are guaranteed in this range, but the following additional conditions apply: a. Refresh commands must be doubled in frequency, therefore reducing the Refresh interval tREFI to 3.9 µs. It is also possible to specify a component with 1X refresh (tREFI to 7.8µs) in the Extended Temperature Range. Please refer to the DIMM SPD for option availability b. If Self-Refresh operation is required in the Extended Temperature Range, then it is mandatory to either use the Manual Self-Refresh mode with Extended Temperature Range capability (MR2 A6 = 0b and MR2 A7 = 1b) or enable the optional Auto Self-Refresh mode (MR2 A6 = 1b and MR2 A7 = 0b). Hynix DDR3 SDRAMs support Auto Self-Refresh and Extended Temperature Range and please refer to Hynix component datasheet and/or the DIMM SPD for tREFI requirements in the Extended Temperature Range.

Rev. 0.2 / Feb. 2010 15 Vref Tolerances The dc-tolerance limits and ac-noise limits for the reference voltages VRefCA and VRefDQ are illustrated in figure below. It shows a valid reference voltage VRef (t) as a function of time. (VRef stands for VRefCA and VRefDQ likewise). VRef (DC) is the linear average of VRef (t) over a very long period of time (e.g. 1 sec). This average has to meet the min/max requirements in the table “Differential Input Slew Rate Definition” on page 22. Furthermore VRef (t) may temporarily deviate from VRef (DC) by no more than +/- 1% VDD. voltage VDD VRef ac-noise VRef(DC) VRef(t) VRef(DC)max VDD/2 VRef(DC)min VSS time Illustration of VRef(DC) tolerance and VRef ac-noise limits The voltage levels for setup and hold time measurements VIH(AC), VIH(DC), VIL(AC), and VIL(DC) are dependent on VRef. “VRef” shall be understood as VRef(DC), as defined in figure above. This clarifies that dc-variations of VRef affect the absolute voltage a signal has to reach to achieve a valid high or low level and therefore the time to which setup and hold is measured. System timing and voltage budgets need to account for VRef(DC) deviations from the optimum position within the data-eye of the input signals. This also clarifies that the DRAM setup/hold specification and derating values need to include time and voltage associated with VRefac-noise. Timing and voltage effects due to ac-noise on VRef up to the specified limit (+/- 1% of VDD) are included in DRAM timings and their associated deratings.

CK and CK have to approximately reach VSEHmin / VSELmax (approximately equal to the ac-levels (VIH (ac) / VIL (ac)) for ADD/CMD signals) in every half-cycle. DQS, DQSL, DQSU, DQS, DQSL have to reach VSEHmin / VSELmax (approximately the ac-levels (VIH (ac) / VIL (ac)) for DQ signals) in every half-cycle preceding and following a valid transition. Note that the applicable ac-levels for ADD/CMD and DQ’s might be different per speed-bin etc. E.g., if VIH.CA(AC150)/VIL.CA(AC150) is used for ADD/CMD signals, then these ac-levels apply also for the singleended signals CK and CK. VDD or VDDQ VSEHmin VSEH VDD/2 or VDDQ/2 CK or DQS VSELmax VSS or VSSQ VSEL time Single-ended requirements for differential signals. Note that, while ADD/CMD and DQ signal requirements are with respect to Vref, the single-ended components of differential signals have a requirement with respect to VDD / 2; this is nominally the same. the transition of single-ended signals through the ac-levels is used to measure setup time. For single-ended components of differential signals the requirement to reach VSELmax, VSEHmin has no bearing on timing, but adds a restriction on the common mode characteristics of these signals.
