Input/Output Functional Description Symbol Type Polarity CK0 Input Positive Edge Function CK0 Input Negative Negative line of the differential pair of system clock inputs that drives the input to the on-DIMM Clock Driver. Edge CKE[1:0] Input CKE HIGH activates, and CKE LOW deactivates internal clock signals, and device input buffers Active High and output drivers of the SDRAMs. Taking CKE LOW provides PRECHARGE POWER-DOWN and SELF REFRESH operation (all banks idle), or ACTIVE POWER DOWN (row ACTIVE in any bank) S[3:0] Input Enables the associated SDRAM command decoder when low and disables decoder when high. When decoder is disabled, new commands are ignored and previous operations continue. These input signals also disable all outputs (except CKE and ODT) of the register(s) on the DIMM when both Active Low inputs are high. When both S[1:0] are high, all register outputs (except CKE, ODT and Chip select) remain in the previous state. For modules supporting 4 ranks, S[3:2] operate similarly to S[1:0] for a second set of register outputs. ODT[1:0] Input Active High On-Die Termination control signals RAS, CAS, WE Input Active Low VREFDQ Supply Reference voltage for DQ0-DQ63 and CB0-CB7 VREFCA Supply Reference voltage for A0-A15, BA0-BA2, RAS, CAS, WE, S0, S1, CKE0, CKE1, Par_In, ODT0 and ODT1. BA[2:0] Input Selects which SDRAM bank of eight is activated. BA0 - BA2 define to which bank an Active, Read, Write or Precharge command is being applied. Bank address also determines mode register is to be accessed during an MRS cycle. A[15:13, 12/BC,11, 10/AP,9:0] Input Provided 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 BA. A12 is also utilized for BL 4/8 identification for "BL on the fly" during CAS command. The address inputs also provide the op-code during Mode Register Set commands. DQ[63:0], CB[7:0] I/O Positive line of the differential pair of system clock inputs that drives input to the on-DIMM Clock Driver. When sampled at the positive rising edge of the clock, CAS, RAS, and WE define the operation to be executed by the SDRAM. Data and Check Bit Input/Output pins Active High Masks write data when high, issued concurrently with input data. VDD, VSS Supply Power and ground for the DDR SDRAM input buffers and core logic. VTT Supply Termination Voltage for Address/Command/Control/Clock nets. DM[8:0] DQS[17:0] I/O DQS[17:0] I/O Positive Edge Positive line of the differential data strobe for input and output data. Negative Edge Negative line of the differential data strobe for input and output data. TDQS/TDQS is applicable for X8 DRAMs only. When enabled via Mode Register A11=1 in MR1, DRAM will enable the same termination resistance function on TDQS/TDQS that is applied to DQS/DQS. When disabled via mode register A11=0 in MR1, DM/TDQS will provide the data mask function and TDQS is not used. X4/X16 DRAMs must disable the TDQS function via mode register A11=0 in MR1 TDQS[17:9], TDQS[17:9] OUT SA[2:0] IN These signals are tied at the system planar to either VSS or VDDSPD to configure the serial SPD EEPROM address range. SDA I/O 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 pull-up. SCL IN 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 pull-up. EVENT OUT (open drain) VDDSPD Supply 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. RESET IN The RESET pin is connected to the RESET pin on the register and to the RESET pin on the DRAM. When low, all register outputs will be driven low and the Clock Driver clocks to the DRAMs and register(s) will be set to low level (the Clock Driver will remain synchronized with the input clock) Par_In IN Parity bit for the Address and Control bus. ("1 " : Odd, "0 ": Even) Err_Out OUT (open drain) TEST Active Low 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 EVENT pin on TS/SPD part. Parity error detected on the Address and Control bus. A resistor may be connected from Err_Out bus line to VDD on the system planar to act as a pull up.

The Normal Temperature Range specifies the temperatures where all DRAM specifications will be supported. During operation, the DRAM case temperature must be maintained between 0-85C under all operating conditions 3. Some applications require operation of the Extended Temperature Range between 85C and 95C 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 3.9us. 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), in this case IDD6 current can be increased around 10~20% than normal Temperature range. 12.

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 of VREF. Furthermore VREF(t) may temporarily deviate from VREF(DC) by no more than 1% VDD. voltage VDD VSS time Figure 1. 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 1. 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 VREF ac-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. - 17 - Rev. 1.5 datasheet Registered DIMM DDR3L SDRAM 13.3 AC and DC Logic Input Levels for Differential Signals 13.3.1 Differential Signals Definition tDVAC Differential Input Voltage (i.e. DQS-DQS, CK-CK) VIH.DIFF.AC.MIN VIH.DIFF.MIN 0.0 half cycle VIL.DIFF.MAX VIL.DIFF.AC.MAX tDVAC time Figure 2.

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, DQS have to reach VSEHmin / VSELmax (approximately the ac-levels ( VIH(AC) / VIL(AC) ) for DQ signals) in every half-cycle proceeding 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 VIH150(AC)/VIL150(AC) is used for ADD/CMD signals, then these ac-levels apply also for the single-ended signals CK and CK . - 19 - Rev. 1.5 datasheet Registered DIMM DDR3L SDRAM VDD or VDDQ VSEH min VSEH VDD/2 or VDDQ/2 CK or DQS VSEL max VSEL VSS or VSSQ time Figure 3. Single-ended requirement 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 singleended 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.

The CL setting and CWL setting result in tCK(AVG).MIN and tCK(AVG).MAX requirements. When making a selection of tCK(AVG), both need to be fulfilled: Requirements from CL setting as well as requirements from CWL setting. 2. tCK(AVG).MIN limits: Since CAS Latency is not purely analog - data and strobe output are synchronized by the DLL - all possible intermediate frequencies may not be guaranteed. An application should use the next smaller JEDEC standard tCK(AVG) value (2.5, 1.875, 1.5, or 1.25 ns) when calculating CL [nCK] = tAA [ns] / tCK(AVG) [ns], rounding up to the next "SupportedCL". 3. tCK(AVG).MAX limits: Calculate tCK(AVG) = tAA.MAX / CL SELECTED and round the resulting tCK(AVG) down to the next valid speed bin (i.e. 3.3ns or 2.5ns or 1.875 ns or 1.25 ns). This result is tCK(AVG).MAX corresponding to CL SELECTED. 4. "Reserved" settings are not allowed. User must program a different value. 5. Any DDR3-1066 speed bin also supports functional operation at lower frequencies as shown in the table which are not subject to Production Tests but verified by Design/ Characterization. 6. Any DDR3-1333 speed bin also supports functional operation at lower frequencies as shown in the table which are not subject to Production Tests but verified by Design/ Characterization. 7. Any DDR3-1600 speed bin also supports functional operation at lower frequencies as shown in the table which are not subject to Production Tests but verified by Design/ Characterization. 8. For devices supporting optional downshift to CL=7 and CL=9, tAA/tRCD/tRP min must be 13.125 ns or lower. SPD settings must be programmed to match. For example, DDR3-1333(CL9) devices supporting downshift to DDR3-1066(CL7) should program 13.125 ns in SPD bytes for tAAmin (Byte 16), tRCDmin (Byte 18), and tRPmin (Byte 20). DDR3-1600(CL11) devices supporting downshift to DDR3-1333(CL9) or DDR3-1066(CL7) should program 13.125 ns in SPD bytes for tAAmin (Byte16), tRCDmin (Byte 18), and tRPmin (Byte 20). Once tRP (Byte 20) is programmed to 13.125ns, tRCmin (Byte 21,23) also should be programmed accordingly.

36 - Registered DIMM datasheet Rev. 1.5 DDR3L SDRAM 19.1 Jitter Notes Specific Note a Unit 'tCK(avg)' represents the actual tCK(avg) of the input clock under operation. Unit 'nCK' represents one clock cycle of the input clock, counting the actual clock edges.ex) tMRD = 4 [nCK] means; if one Mode Register Set command is registered at Tm, another Mode Register Set command may be registered at Tm+4, even if (Tm+4 - Tm) is 4 x tCK(avg) + tERR(4per),min. Specific Note b These parameters are measured from a command/address signal (CKE, CS, RAS, CAS, WE, ODT, BA0, A0, A1, etc.) transition edge to its respective clock signal (CK/CK) crossing. The spec values are not affected by the amount of clock jitter applied (i.e. tJIT(per), tJIT(cc), etc.), as the setup and hold are relative to the clock signal crossing that latches the command/address. That is, these parameters should be met whether clock jitter is present or not. Specific Note c These parameters are measured from a data strobe signal (DQS, DQS) crossing to its respective clock signal (CK, CK) crossing. The spec values are not affected by the amount of clock jitter applied (i.e. tJIT(per), tJIT(cc), etc.), as these are relative to the clock signal crossing. That is, these parameters should be met whether clock jitter is present or not. Specific Note d These parameters are measured from a data signal (DM, DQ0, DQ1, etc.) transition edge to its respective data strobe signal (DQS, DQS) crossing. Specific Note e For these parameters, the DDR3 SDRAM device supports tnPARAM [nCK] = RU{ tPARAM [ns] / tCK(avg) [ns] }, which is in clock cycles, assuming all input clock jitter specifications are satisfied. For example, the device will support tnRP = RU{tRP / tCK(avg)}, which is in clock cycles, if all input clock jitter specifications are met. This means: For DDR3-800 6-6-6, of which tRP = 15ns, the device will support tnRP = RU{tRP / tCK(avg)} = 6, as long as the input clock jitter specifications are met, i.e. Precharge command at Tm and Active command at Tm+6 is valid even if (Tm+6 - Tm) is less than 15ns due to input clock jitter. Specific Note f When the device is operated with input clock jitter, this parameter needs to be derated by the actual tERR(mper),act of the input clock, where 2 <= m <= 12. (output deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR3-800 SDRAM has tERR(mper),act,min = - 172 ps and tERR(mper),act,max = + 193 ps, then tDQSCK,min(derated) = tDQSCK,min - tERR(mper),act,max = - 400 ps - 193 ps = - 593 ps and tDQSCK,max(derated) = tDQSCK,max - tERR(mper),act,min = 400 ps + 172 ps = + 572 ps. Similarly, tLZ(DQ) for DDR3-800 derates to tLZ(DQ),min(derated) = - 800 ps - 193 ps = - 993 ps and tLZ(DQ),max(derated) = 400 ps + 172 ps = + 572 ps. (Caution on the min/max usage!) Note that tERR(mper),act,min is the minimum measured value of tERR(nper) where 2 <= n <= 12, and tERR(mper),act,max is the maximum measured value of tERR(nper) where 2 <= n <= 12. Specific Note g When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJIT(per),act of the input clock. (output deratings are relative to the SDRAM input clock.) For example, if the measured jitter into a DDR3-800 SDRAM has tCK(avg),act = 2500 ps, tJIT(per),act,min = - 72 ps and tJIT(per),act,max = + 93 ps, then tRPRE,min(derated) = tRPRE,min + tJIT(per),act,min = 0.9 x tCK(avg),act + tJIT(per),act,min = 0.9 x 2500 ps - 72 ps = + 2178 ps. Similarly, tQH,min(derated) = tQH,min + tJIT(per),act,min = 0.38 x tCK(avg),act + tJIT(per),act,min = 0.38 x 2500 ps - 72 ps = + 878 ps. (Caution on the min/ max usage!) - 37 - Registered DIMM datasheet Rev. 1.5 DDR3L SDRAM 19.2 Timing Parameter Notes 1. Actual value dependant upon measurement level definitions which are TBD. 2. Commands requiring a locked DLL are: READ (and RAP) and synchronous ODT commands. 3. The max values are system dependent. 4. WR as programmed in mode register 5. Value must be rounded-up to next higher integer value 6. There is no maximum cycle time limit besides the need to satisfy the refresh interval, tREFI. 7. For definition of RTT turn-on time tAON see "Device Operation & Timing Diagram Datasheet" 8. For definition of RTT turn-off time tAOF see "Device Operation & Timing Diagram Datasheet". 9. tWR is defined in ns, for calculation of tWRPDEN it is necessary to round up tWR / tCK to the next integer. 10. WR in clock cycles as programmed in MR0 11. The maximum read postamble is bound by tDQSCK(min) plus tQSH(min) on the left side and tHZ(DQS)max on the right side. See "Device Operation & Timing Diagram Datasheet. 12. Output timing deratings are relative to the SDRAM input clock. When the device is operated with input clock jitter, this parameter needs to be derated by TBD 13. Value is only valid for RON34 14. Single ended signal parameter. Refer to chapter 8 and chapter 9 for definition and measurement method. 15. tREFI depends on TOPER 16. tIS(base) and tIH(base) values are for 1V/ns CMD/ADD single-ended slew rate and 2V/ns CK, CK differential slew rate, Note for DQ and DM signals, VREF(DC) = VREFDQ(DC). For input only pins except RESET, VREF(DC)=VREFCA(DC). See "Address/Command Setup, Hold and Derating" on component datasheet. 17. tDS(base) and tDH(base) values are for 1V/ns DQ single-ended slew rate and 2V/ns DQS, DQS differential slew rate. Note for DQ and DM signals, VREF(DC)= VREFDQ(DC). For input only pins except RESET, VREF(DC)=VREFCA(DC). See "Data Setup, Hold and Slew Rate Derating" on component datasheet. 18. Start of internal write transaction is defined as follows ; For BL8 (fixed by MRS and on-the-fly) : Rising clock edge 4 clock cycles after WL. For BC4 (on-the-fly) : Rising clock edge 4 clock cycles after WL For BC4 (fixed by MRS) : Rising clock edge 2 clock cycles after WL 19. The maximum read preamble is bound by tLZDQS(min) on the left side and tDQSCK(max) on the right side. See "Device Operation & Timing Diagram Datasheet" 20. CKE is allowed to be registered low while operations such as row activation, precharge, autoprecharge or refresh are in progress, but power-down IDD spec will not be applied until finishing those operations. 21. Although CKE is allowed to be registered LOW after a REFRESH command once tREFPDEN(min) is satisfied, there are cases where additional time such as tXPDLL(min) is also required. See "Device Operation & Timing Diagram Datasheet". 22. Defined between end of MPR read burst and MRS which reloads MPR or disables MPR function. 23. One ZQCS command can effectively correct a minimum of 0.5 % (ZQCorrection) of RON and RTT impedance error within 64 nCK for all speed bins assuming the maximum sensitivities specified in the 'Output Driver Voltage and Temperature Sensitivity' and 'ODT Voltage and Temperature Sensitivity' tables. The appropriate interval between ZQCS commands can be determined from these tables and other application specific parameters. One method for calculating the interval between ZQCS commands, given the temperature (Tdriftrate) and voltage (Vdriftrate) drift rates that the SDRAM is subject to in the application, is illustrated. The interval could be defined by the following formula: ZQCorrection (TSens x Tdriftrate) + (VSens x Vdriftrate) where TSens = max(dRTTdT, dRONdTM) and VSens = max(dRTTdV, dRONdVM) define the SDRAM temperature and voltage sensitivities. For example, if TSens = 1.5% /C, VSens = 0.15% / mV, Tdriftrate = 1C / sec and Vdriftrate = 15 mV / sec, then the interval between ZQCS commands is calculated as: 0.5 (1.5 x 1) + (0.15 x 15) = 0.133 ~ ~ 128ms 24. n = from 13 cycles to 50 cycles. This row defines 38 parameters. 25. tCH(abs) is the absolute instantaneous clock high pulse width, as measured from one rising edge to the following falling edge. 26. tCL(abs) is the absolute instantaneous clock low pulse width, as measured from one falling edge to the following rising edge. 27. The tIS(base) AC150 specifications are adjusted from the tIS(base) specification by adding an additional 100 ps of derating to accommodate for the lower alternate threshold of 150 mV and another 25 ps to account for the earlier reference point [(175 mv - 150 mV) / 1 V/ns]. 28. Pulse width of a input signal is defined as the width between the first crossing of VREF(DC) and the consecutive crossing of VREF(DC) 29. tDQSL describes the instantaneous differential input low pulse width on DQS-DQS, as measured from one falling edge to the next consecutive rising edge. 30. tDQSH describes the instantaneous differential input high pulse width on DQS-DQS, as measured from one rising edge to the next consecutive falling edge. 31. tDQSH, act + tDQSL, act = 1 tCK, act ; with tXYZ, act being the actual measured value of the respective timing parameter in the application. 32. tDSH, act + tDSS, act = 1 tCK, act ; with tXYZ, act being the actual measured value of the respective timing parameter in the application. - 38 - Rev. 1.5 datasheet Registered DIMM DDR3L SDRAM 20.
