Note:To Enter SelfRefresh Mode
1. CS#,RAS#&CAS#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 SelfRefresh mode as long as CKE stays “low”.
To Exit SelfRefresh Mode
1. System clock restart and be stable before returning CKE high.
2. Enable CKE and CKE should be set high for minimum time of tSRX.
3. CS#starts from high.
4. Minimum tRC is required after CKE going high to complete SelfRefresh exit.
5. 8192 cycles of burst AutoRefresh is required before SelfRefresh entry and after SelfRefresh exit if the system uses burst refresh.
DQ
Once the device enters SelfRefresh mode,minimum tRAS is required before exit from SelfRefresh.
