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

4) When operating this product in the 85 °C to 95 °C T

 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
