Input
Cross point
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

When sampled at the cross point of the rising edge of CK and falling edge of CK, signals CAS, RAS, and WE define the operation to be executed by the SDRAM.
Selects which DDR3 SDRAM internal bank of eight is activated.
Asserts on-die termination for DQ, DM, DQS, and DQS signals if enabled via the
DDR3 SDRAM mode register.
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 or
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,

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 BA0BAn inputs. If AP is low, then BA0-BAn are used to define which bank to precharge.
A12(BC) is sampled during READ and WRITE commands to determine if burst chop
(on-thefly) 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.

at the leading edge of the data window. DQS signals are complements, and timing is
relative to the crosspoint of respective DQS and DQS.

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 85°… and
95°… 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.
(This double refresh requirement may not apply for some devices.) It is also possible to specify a component
with 1X refresh (tREFI to 7.8µs) in the Extended Temperature Range. Please refer to supplier data sheet and/
or the DIMM SPD for option avail ability.
b) If Self-Refresh operation is required in the Extended Temperature Range, than it is mandatory to either use the
Manual Self-Refresh mode with Extended Temperature Range capability (MR2 A6 = 0band MR2 A7 = 1b) or
enable the optional Auto Self-Refresh mode (MR2 A6 = 1b and MR2 A7 = 0b).

1. For DQ and DM, Vref = VrefDQ. For input only pins except RESET#, Vref = VrefCA.
2. The “t.b.d.” entries might change based on overshoot and undershoot specification.
3. The ac peak noise on VRef may not allow VRef to deviate from VRef (DC) by more than +/-1% VDD
(for reference: approx. +/- 15 mV).
For reference: approx. VDD/2 +/- 15 mV.
The dc-tolerance limits and ac-noise limits for the reference voltages VRefCA and VRefDQ are illustrated in figure
5.2.1. 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 Table 1. Furthermore VRef (t) may temporarily deviate from VRef (DC) by no more than
+/- 1% VDD.

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.
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.

5.7 IDD 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, IDD6TC 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).
•
“FLOATING” is defined as inputs are VREF - VDD/2.
•
Timing used for IDD and IDDQ Measurement-Loop Patterns are provided in Table 1 on Page 26.
•
Basic IDD and IDDQ Measurement Conditions are described in Table 2 on page 26.
•
Detailed IDD and IDDQ Measurement-Loop Patterns are described in Table 3 on page 30 through Table 10 on
page 36.
•
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}

*Speed Bin Table Notes*
Absolute Specification (TOPER; VDDQ = VDD = 1.5V +/- 0.075 V);
Notes:
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 (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’.
3. tCK(AVG).MAX limits: Calculate tCK (AVG) = tAA.MAX / CLSELECTED 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
CLSELECTED.
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 supplier’s data sheet and 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.
