Abbreviations:

Notes:
1. After CKEs low-to-high transition to exit self refresh mode. And a time of t
RC
(min) has to be elapse after CKEs low-to-high
transition to issue a new command.
2. CKE low to high transition is asynchronous as if restart internal clock.
A minimum setup time “t
SS
+ one clock” must be satisfy before any command other than exit.
3. Power down and self refresh can be entered only from the all banks idle state.
4. Must be a legal command.
