The system clock inputs. 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 S

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 cross point of the rising edge of CK and falling edge of CK autoprecharge operation at the end of the burst read or write cycle. If AP is high, autoprecharge is selected and BA0BAn 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 performed (HIGH, no burst chop; LOW, burst chopped)

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.

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. In Read mode, the data strobe is sourced by the DDR3 SDRAMs and is sent at the leading edge of the data window. DQS the crosspoint of respective DQS and DQS

3. Some applications require operation of the Extended Temperature Range between 85°C and 95°C 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

15.3.1 Speed Bin Table Notes

Absolute Specification [T

NOTE :

1. 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 guar-

anteed. 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. For example, 49.125ns (tRASmin + tRPmin=36ns+13.125ns) for DDR3-1333(CL9) and 48.125ns (tRASmin+tRPmin=35ns+13.125ns) for DDR3-1600(CL11).

9. DDR3 800 AC timing apply if DRAM operates at lower than 800 MT/s data rate.

10. For CL5 support DIMM SPD include CL5 on supportable CAS Latency(Byte 14-bit1 set HIGH).

16.1 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

edge to its respective clock signal (CK/CK 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

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

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.

) crossing. The spec values are not affected by the amount of clock jitter applied (i.e.

, RAS, CAS, WE, ODT, BA0, A0, A1, etc.) transition

) crossing to its respective clock signal (CK, CK) crossing.

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!)

16.2 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 T

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,

(DC) = V

REF

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,

(DC)= V

REF

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 sub-

ject to in the application, is illustrated. The interval could be defined by the following formula:

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 = 1°C / sec and Vdriftrate = 15 mV / sec, then the interval between ZQCS commands is calculated as:

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 alter-

nate 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 V

29. tDQSL describes the instantaneous differential input low pulse width on DQS-DQS

(DC) and the consecutive crossing of V
