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.

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).

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.
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.

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). DDR3 SDRAMs support Auto
Self-Refresh and Extended Temperature Range and please refer to component datasheet and/or the DIMM
SPD for tREFI requirements in the Extended Temperature Range.

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.

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.

Single-ended requirements for differential signals
Each individual component of a differential signal (CK, DQS, DQSL, DQSU, CK, DQS, DQSL, of DQSU) has
also to comply with certain requirements for single-ended signals.
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.

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.

Notes:
1. For CK, CK use VIH/VIL (ac) of ADD/CMD; for strobes (DQS, DQS, DQSL, DQSL, DQSU, DQSU) use VIH/VIL (ac)
of DQs.
2. VIH (ac)/VIL (ac) for DQs is based on VREFDQ; VIH (ac)/VIL (ac) for ADD/CMD is based on VREFCA; if a reduced
ac-high or ac-low level is used for a signal group, then the reduced level applies also here.
3. These values are not defined; however, the single-ended signals Ck, CK, DQS, DQS, DQSL, DQSL, DQSU, DQSU
need to be within the respective limits (VIH (dc) max, VIL (dc) min) for single-ended signals as well as the limitations for overshoot and undershoot. Refer to "Overshoot and Undershoot Specifications" on page 27.
Differential Input Cross Point Voltage
To guarantee tight setup and hold times as well as output skew parameters with respect to clock and
strobe, each cross point voltage of differential input signals (CK, CK and DQS, DQS) must meet the
requirements in the table below. The differential input cross point voltage VIX is measured from the actual
cross point of true and complement signals to the midlevel between of VDD and VSS

slew rate of CK - CK is larger than 3 V/ns.
Refer to the table "Single-ended levels for CK, DQS, DQSL, DQSU, CK, DQS, DQSL or DQSU" on page 20
for VSEL and VSEH standard values.
2. The relation between Vix Min/Max and VSEL/VSEH should satisfy following.
(VDD/2) + Vix (Min) - VSEL ≥ 25mV
VSEH - ((VDD/2) + Vix(Max)) ≥ 25mV

Note 1): In two cases, a maximum slew rate of 6V/ns applies for a single DQ signal within a byte lane.
Case 1 is a defined for a single DQ signal within a byte lane which is switching into a certain direction (either from high
to low or low to high) while all remaining DQ signals in the same byte lane are static (i.e. they stay at either high or low).
Case 2 is a defined for a single DQ signal within a byte lane which is switching into a certain direction (either from high
to low or low to high) while all remaining DQ signals in the same byte lane switching into the opposite direction (i.e. from
low to high of high to low respectively). For the remaining DQ signal switching in to the opposite direction, the regular
maximum limite of 5 V/ns applies.

Reference Load for AC Timing and Output Slew Rate
Figure below represents the effective reference load of 25 ohms used in defining the relevant AC timing
parameters of the device as well as output slew rate measurements.
It is not intended as a precise representation of any particular system environment or a depiction of the
actual load presented by a production tester. System designers should use IBIS or other simulation tools to
correlate the timing reference load to a system environment. Manufacturers correlate to their production
test conditions, generally one or more coaxial transmission lines terminated at the tester electronics.

Speed Bin Table Notes
Absolute Specification (TOPER; VDDQ = VDD = 1.5V +/- 0.075 V);
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 guaranteed. An application should
use the next smaller JEDEC standard tCK(AVG) value (3.0, 2.5, 1.875, 1.5, or 1.25 ns) when calculating CL [nCK] = tAA [ns] / tCK(AVG) [ns], rounding up to the next ‘Supported CL’, where tCK(AVG) =
3.0 ns should only be used for CL = 5 calculation.
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. ‘Optional’ settings allow certain devices in the industry to support this setting, however, it is not a mandatory feature. Refer to DIMM data sheet and/or the DIMM SPD information if and how this setting is
supported.
6. 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.
7. 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.
8. 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.
9. DDR3 SDRAM devices supporting optional down binning to CL=7 and CL=9, and tAA/tRCD/tRP must
be 13.125 ns or lower. SPD settings must be programmed to match. For example, DDR3-1333H
devices supporting down binning to DDR3-1066F should program 13.125 ns in SPD bytes for tAAmin
(Byte 16), tRCDmin (Byte 18), and tRPmin (Byte 20). DDR3-1600K devices supporting down binning to
DDR3-1333H or DDR3-1600F should program 13.125 ns in SPD bytes for tAAmin (Byte 16), 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 = 36 ns + 13.125
ns) for DDR3-1333H and 48.125ns (tRASmin + tRPmin = 35 ns + 13.125 ns) for DDR3-1600K.
10. For CL5 support, refer to DIMM SPD information. DRAM is required to support CL5. CL5 is not mandatory in SPD coding.
11. DDR3 SDRAM devices supporting optional down binning to CL=11, CL=9 and CL=7, tAA/tRCD/tRPmin
must be 13.125ns. SPD setting must be programed to match. For example, DDR3-1866M devices supporting down binning to DDR3-1600K or DDR3-1333H or 1066F should program 13.125ns in SPD
bytes for tAAmin(byte16), tRCDmin(byte18) and tRPmin(byte20). Once tRP (byte20) is programmed
to
13.125ns, tRCmin(byte 21,23) also should be programmed accordingly. For example,
47.125ns(tRASmin + tRPmin = 34ns + 13.125ns)

IDD and IDDQ Specification Parameters and Test Conditions
IDD and IDDQ Measurement Conditions
In this chapter, IDD and IDDQ measurement conditions such as test load and patterns are defined. Figure
1. shows the setup and test load for IDD and IDDQ measurements.
•
IDD currents (such as IDD0, IDD1, IDD2N, IDD2NT, IDD2P0, IDD2P1, IDD2Q, IDD3N, IDD3P, IDD4R,
IDD4W, IDD5B, IDD6, IDD6ET and IDD7) are measured as time-averaged currents with all VDD balls
of the DDR3 SDRAM under test tied together. Any IDDQ current is not included in IDD currents.
•
IDDQ currents (such as IDDQ2NT and IDDQ4R) are measured as time-averaged currents with all
VDDQ balls of the DDR3 SDRAM under test tied together. Any IDD current is not included in IDDQ currents.
Attention: IDDQ values cannot be directly used to calculate IO power of the DDR3 SDRAM. They can
be used to support correlation of simulated IO power to actual IO power as outlined in Figure 2. In
DRAM module application, IDDQ cannot be measured separately since VDD and VDDQ are using one
merged-power layer in Module PCB.
For IDD and IDDQ measurements, the following definitions apply:
•
”0” and “LOW” is defined as VIN <= VILAC(max).
•
”1” and “HIGH” is defined as VIN >= VIHAC(max).
•
“MID_LEVEL” is defined as inputs are VREF = VDD/2.
•
Timing used for IDD and IDDQ Measurement-Loop Patterns are provided in Table 1.
•
Basic IDD and IDDQ Measurement Conditions are described in Table 2.
•
Detailed IDD and IDDQ Measurement-Loop Patterns are described in Table 3 through Table 10.
•
IDD Measurements are done after properly initializing the DDR3 SDRAM. This includes but is not limited to setting
RON = RZQ/7 (34 Ohm in MR1);
Qoff = 0B (Output Buffer enabled in MR1);
RTT_Nom = RZQ/6 (40 Ohm in MR1);
RTT_Wr = RZQ/2 (120 Ohm in MR2);
TDQS Feature disabled in MR1
•
Attention: The IDD and IDDQ Measurement-Loop Patterns need to be executed at least one time
before actual IDD or IDDQ measurement is started.
•
Define D = {CS, RAS, CAS, WE}:= {HIGH, LOW, LOW, LOW}
Define D = {CS, RAS, CAS, WE}:= {HIGH, HIGH, HIGH, HIGH}
