NOTES:
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 SDRAM immediately prior to clock edge
n
.
3. COMMANDn is the command registered at clock edge
n
, and ACTONn 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 all banks idle state in time for clock edge
n+1
(provided that t
CKS
is met)
.
6. Exiting self refresh at clock edge
n
will put the device in all banks idle state once t
XSR
is met. COMMAND INHIBIT or NOP commands
should be issued on clock edges occurring during the t
XSR
period. A minimum of two NOP commands must be sent during t
XSR
period.
7. After exiting clock suspend at clock edge
n
, the device will resume operation and recognize the next command at clock edge
n+1
.
