NOTE:
Stress 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 greater than those indicated in the operational sections of this specication is not

specified for the clock pin) prior to CKE going back
HIGH. Once CKE is HIGH, the SDRAM must have NOP
commands issued (a minimum of two clocks) for tXSR,
because time is required for the completion of any internal
refresh in progress.
Upon exiting the self refresh mode, AUTO REFRESH
commands must be issued as both SELF REFRESH and
AUTO REFRESH utilize the row refresh counter.
