All the DDR3L SDRAM addr/cntl inputs are sampled on the crossing of positive edge of CK and negative edge of CK. Output (read) data is reference to the crossing of CK and CK (Both directions of crossing). Activates the 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 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. This signal provides for external rank selection on systems with multiple ranks. RAS, CAS, and WE (ALONG WITH S) define the command being entered. When high, termination resistance is enabled for all DQ, DQS, DQS and DM pins, assuming this function is enabled in the Mode Register 1 (MR1). Reference voltage for SSTL15 I/O inputs. Reference voltage for SSTL 15 command/address inputs. Power supply for the DDR3L SDRAM output buffers to provide improved noise immunity. For all current DDR3L unbuffered DIMM designs, VDDQ shares the same power plane as VDD pins. — Selects which SDRAM bank of eight is activated. During a Bank Activate command cycle, Address input defines the row address (RA0–RA15). During a Read or Write command cycle, Address input defines the column address. 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, BA1, BA2 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, BA1, BA2 to control which bank(s) to precharge. If AP is high, all banks will be precharged regardless of the state of BA0, BA1 or BA2. If AP is low, BA0, BA1 and BA2 are used to define which bank to precharge. A12(BC) is sampled during READ and WRITE commands to determine if burst chop (on-the-fly) will be performed (HIGH, no burst chop; LOW, burst chopped). Data and Check Bit Input/Output pins. 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. Power and ground for the DDR3 SDRAM input buffers, and core logic. VDD and VDDQ pins are tied to VDD/VDDQ planes on these modules.

These signals are tied at the system planar to either VSS or VDDSPD to configure the serial SPD EEPROM address range. This bidirectional pin is used to transfer data into or out of the SPD EEPROM. An external resistor may be connected from the SDA bus line to VDDSPD to act as a pullup on the system board. This signal is used to clock data into and out of the SPD EEPROM. An external resistor may be connected from the SCL bus time to VDDSPD to act as a pullup on the system board. Power supply for SPD EEPROM. This supply is separate from the VDD/VDDQ power plane. EEPROM supply is operable from 3.0V to 3.6V.

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 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.

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.

Rev. 0.1 / Nov. 2009 17 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 24. 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.

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.
