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. 3. VDD and VDDQ must be within 300mV of each other at all times; and VREF must be not greater than 0.6 × VDDQ, When VDD and VDDQ are less than 500mV; VREF may be equal to or less than 300mV. 4. DDR3 SDRAM component specification. Caution Exposing the device to stress above those listed in Absolute Maximum Ratings could cause permanent damage. The device is not meant to be operated under conditions outside the limits described in the operational section of this specification Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Operating Temperature Condition Parameter Symbol Rating Unit Notes Operating case temperature TC 0 to +95 °C 1, 2, 3 Notes: 1. Operating temperature is the case surface temperature on the center/top side of the DRAM. 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°C to +85°C under all operating conditions. 3. Some applications require operation of the DRAM in 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 3.9µs. (This double refresh requirement may not apply for some devices.) 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 bit [A6, A7] = [0, 1]) or enable the optional Auto Self-Refresh mode (MR2 bit [A6, A7] = [1, 0]).

All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of /CK. Output (read) data is referenced to the crossings of CK and /CK (both directions of crossing). /CS (input pin) All commands are masked when /CS is registered high. /CS provides for external rank selection on systems with multiple ranks. /CS is considered part of the command code. /RAS, /CAS, and /WE (input pins) /RAS, /CAS and /WE (along with /CS) define the command being entered. A0 to A13 (input pins) Provided the row address for active commands and the column address for read/write commands to select one location out of the memory array in the respective bank. (A10(AP) and A12(/BC) have additional functions, see below) The address inputs also provide the op-code during mode register set commands. [Address Pins Table] Address (A0 to A13) Row address (RA) Column address (CA) AX0 to AX13 AY0 to AY9 Notes A10(AP) (input pin) A10 is sampled during read/write commands to determine whether auto-precharge should be performed to the accessed bank after the read/write operation. (high: auto-precharge; low: no auto-precharge) 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 bank addresses (BA). A12 (/BC) (input pin) A12 is sampled during read and write commands to determine if burst chop (on-the-fly) will be performed. (A12 = high: no burst chop, A12 = low: burst chopped.) BA0 to BA2 (input pins) BA0, BA1 and BA2 define to which bank an active, read, write or precharge command is being applied. BA0 and BA1 also determine if a mode register is to be accessed during a MRS cycle.

Data Sheet E1235E40 (Ver. 4.0) 14 EBJ21EE8BAFA CKE (input pin) CKE high activates, and CKE low deactivates, internal clock signals and device input buffers and output drivers. Taking CKE low provides precharge power-down and self-refresh operation (all banks idle), or active power-down (row active in any bank). CKE is asynchronous for self-refresh exit. After VREF has become stable during the power-on and initialization sequence, it must be maintained for proper operation of the CKE receiver. For proper self-refresh entry and exit, VREF must be maintained to this input. CKE must be maintained high throughout read and write accesses. Input buffers, excluding CK, /CK, ODT and CKE are disabled during power-down. Input buffers, excluding CKE, are disabled during self-refresh. DQ and CB (input and output pins) Bi-directional data bus. DQS and /DQS (input and output pin) Output with read data, input with write data. Edge-aligned with read data, centered in write data. The data strobe DQS is paired with differential signals /DQS to provide differential pair signaling to the system during READs and WRITEs. ODT (input pins) ODT (registered high) enables termination resistance internal to the DDR3 SDRAM. When enabled, ODT is only applied to each DQ, DQS, /DQS, DM. The ODT pin will be ignored if the mode register (MR1) is programmed to disable ODT. DM (input pins) DM is the reference signal of the data input mask function. DMs are sampled at the cross point of DQS and /DQS. VDD (power supply pins) 1.5V is applied. (VDD is for the internal circuit.) VDDSPD (power supply pin) 3.3V is applied (For serial EEPROM). VSS (power supply pin) Ground is connected. VTT (power supply pin) I/O termination supply for SDRAM. VREFDQ (power supply) Reference voltage for DQ. VREFCA (power supply) Reference voltage for CA. /RESET (input pin) /RESET is negative active signal (active low) and is referred to GND. /EVENT (output pin) Temperature alert output.

It is necessary to avoid undue mechanical stress on these components to prevent damaging them. In particular, do not push module cover or drop the modules in order to protect from mechanical defects, which would be electrical defects. When re-packing memory modules, be sure the modules are not touching each other. Modules in contact with other modules may cause excessive mechanical stress, which may damage the modules. MDE0202 NOTES FOR CMOS DEVICES 1 PRECAUTION AGAINST ESD FOR MOS DEVICES Exposing the MOS devices to a strong electric field can cause destruction of the gate oxide and ultimately degrade the MOS devices operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it, when once it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. MOS devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. MOS devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor MOS devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS DEVICES No connection for CMOS devices input pins can be a cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. The unused pins must be handled in accordance with the related specifications. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Power-on does not necessarily define initial status of MOS devices. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the MOS devices with reset function have not yet been initialized. Hence, power-on does not guarantee output pin levels, I/O settings or contents of registers. MOS devices are not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for MOS devices having reset function.
