with CKE should be low at the same clock cycle.
2. After 1 clock cycle, all the inputs including the system clock can be don’t care except for CKE.
3. The device remains in self refresh mode as long as CKE stays “Low”.
(cf.) Once the device enters self refresh mode, minimum tRAS is required before exit from self refresh.
TO EXIT SELF REFRESH MODE
4. System clock restart and be stable before returning CKE high.
5.

starts from high.
6. Minimum tRC is required after CKE going high to complete self refresh exit.
7. Before/After self refresh mode, AUTO REFRESH commands must be issued every 15.6
μ
s or less as both SELF
REFRESH and AUTO REFRESH utilize the row refresh counter.
