6. Absolute Maximum Ratings

6.1 Absolute Maximum DC Ratings

[ Table 4 ] Absolute Maximum DC Ratings

NOTE :

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 rating 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.

equal to or less than 300mV.

6.2 DRAM Component Operating Temperature Range

[ Table 5 ] Temperature Range

NOTE :

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 main-

tained between 0-85

°C under all operating conditions

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
