Electrical Characteristics
This chapter describes the electrical characteristics.
5.1
Absolute Maximum Ratings
Caution is needed not to exceed absolute maximum ratings of the DRAM device listed in Table 18 at any time.
TABLE 18
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.

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.
3) During operation, the DRAM case temperature must be maintained between 0 - 95 °C under all other specification parameters.
4) Above 85
°C the Auto-Refresh command interval has to be reduced to t
REFI= 3.9 μs.
5) When operating this product in the 85 °C to 95 °C
T
CASE temperature range, the High Temperature Self Refresh has to be enabled by
setting EMR(2) bit A7 to 1. When the High Temperature Self Refresh is enabled there is an increase of
I
DD6 by approximately 50%.
