is dened as a signal cycling within timing constraints
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.
* Self refresh available in commercial and industrial temperatures only.

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 implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
