Notes
:
1. Self refresh can enter only from the all banks idle state.
2. Power Down occurs when all banks are idle; this mode is referred to as precharge power down.
3. Power Down occurs when there is a row active in any bank; this mode is referred to as active power down.
Remark: H = High level, L = Low level, X = High or Low level (Don’t care), V = Valid data
