spec i fied for the clock pin) prior to CKE going back
HIGH. Once CKE is HIGH, the SDRAM must have NOP
commands is sued (a minimum of two clocks) for t
because time is required for the com ple tion of any internal
refresh in progress.
Upon exiting the self refresh mode, AUTO REFRESH
com mands must be issued as both SELF REFRESH and
AUTO REFRESH utilize the row refresh counter.
NOTE:
Stress greater than those listed under "Absolute Maximum Ratings" may cause per ma nent damage to the device. This is a stress rating
only and func tion al op er a tion of the device at these or any other conditions greater than those in di cat ed in the operational sections of
this specifi cation is not implied. Exposure to ab so lute maximum rating con di tions for extended periods may affect reliability.
NOTE:
Refer to Application Note “PBGA Thermal Resistance Correlation” at www.wedc.com in the
application notes section for modeling conditions.
