NOTE:

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 of the SyncFlash memory immediately prior to clock edge n.

3. “COMMANDn” is the command registered at clock edge n and “ACTIONn” is a result of COMMANDn.

4. All states and sequences not shown are illegal or reserved.

5. Exiting power-down at clock edge n will put the device in the idle state in time for clock edge n + 1 (provided that tCKS

is met).

6. After exiting clock suspend at clock edge n, the device will resume operation and recognize the next command at clock

edge n + 1.
