Notes
1)2)3)4)
1) CKEn is the logic state of CKE at clock edge n; CKEn-1 was the state of CKE at the previous clock edge.
2) Current state is the state immediately prior to clock edge n.
3) COMMAND n is the command registered at clock edge n; ACTION n is a result of COMMAND n.
4) All states and sequences not shown are illegal or reserved.
5) DESELECT or NOP commands should be issued on any clock edges occurring during
t
RC
period.
6) Exit from DEEP POWER DOWN requires the same command sequence as for power-up initialization.
