Truth Table 2: Clock Enable (CKE)
1. CKE n is the logic state of CKE at clock edge n: CKE n-1 was the state of CKE at the previous clock edge.
2. Current state is the state of the DDR SDRAM immediately prior to clock edge n.
3. Command n is the command registered at clock edge n, and action n is a result of command n.
4. All states and sequences not shown are illegal or reserved.

1. Deselect or NOP commands should be issued on any clock edges occurring during the Self Refresh Exit (t
XSNR
) period. A minimum of
200 clock cycles are needed before applying a read command to allow the DLL to lock to the input clock.
