ABSOLUTE MAXIMUM RATINGS
Note :
1. Stresses greater than those listed may cause permanent damage to the device. This is a stress rating only, and device functional
operation at or above the conditions indicated is not implied. Expousure to absolute maximum rating conditions for extended
periods may affect reliablility.
2. If the DRAM case temperature is Above 85
o
C,
the Auto-Refresh command interval has to be reduced to tREFI=3.9
.
For Measurement conditions of T
CASE
, please refer to the JEDEC document JESD51-2.
3. Up to 9850 ft.
