1) When V_DD and V_DDQ and V_DDL are less than 500 mV; V_REF may be equal to or less than 300 mV.
2) Storage Temperature is the case surface temperature on the center/top side of the DRAM.
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. During operation, the DRAM case
temperature must be maintained between 0 - 95 °C under all other specification parameters.
3) Above 85 °C the Auto-Refresh command interval has to be reduced to t_REFI= 3.9 µs
4) 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 %
