1. 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 rat-
ing conditions for extended periods may affect reliability.

2. Storage Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement 

conditions, please refer to JESD51-2 standard.

3. VDD and VDDQ must be within 300mV of each other at all times; and VREF must not be greater than 

0.6XVDDQ,When VDD and VDDQ are less than 500mV; VREF may be equal to or less than 300mV.



1. Operating Temperature TOPER is the case surface temperature on the center / top side of the DRAM. For mea-

surement conditions, please refer to the JEDEC document JESD51-2.

2. The Normal Temperature Range specifies the temperatures where all DRAM specifications will be supported. Dur-

ing operation, the DRAM case temperature must be maintained between 0 - 85

o

C under all operating conditions.

3. Some applications require operation of the DRAM in the Extended Temperature Range between 85

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. DDR3 SDRAMs support Auto Self-Refresh and Extended Temperature Range and please refer to component 

datasheet and/or the DIMM SPD for tREFI requirement in the Extended Temperature Range.
