Electrical Characteristics
3.1
Absolute Maximum Ratings
Caution is needed not to exceed absolute maximum ratings of the DRAM device listed in
Table 8
at any time.
TABLE 8
Absolute Maximum Ratings
Attention: 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.

CASE
1) Operating Temperature is the case surface temperature on the center / top side of the DRAM.
2) The operating temperature range are the temperatures where all DRAM specification will be supported. During operation, the DRAM case
temperature must be maintained between 0 - 95 °C under all other specification parameters.
