Self-Refresh Recovery
Power-Down (P.D.)
Both Banks Idle
Any state
other than
listed above
Notes:
1. H : High level, L : low level, X : High or low level (Don’t care).
2. CKE Low to High transition will re-enable CLK and other inputs asynchronously. A minimum
setup time must be satisfied
before any command other than EXIT.
3. Power down and Self refresh can be entered only from the both banks idle state.
4. Must be legal command as defined in Operative Command Table.
5. Illegal if t
XSR
is not satisfied.
