down deactivates the input and output buffers, excluding CK, CK#, and CKE. For maxi-
mum power savings, the DLL is frozen during precharge power-down mode. Exiting
power-down requires the device to be at the same voltage and frequency as when it
entered power-down. However, power-down duration is limited by the refresh require-
ments of the device (
While in power-down, CKE LOW and a stable clock signal must be maintained at the
inputs of the DDR SDRAM, while all other input signals are “Don’t Care.” The power-
down state is synchronously exited when CKE is registered HIGH (in conjunction with a
NOP or DESELECT command). A valid executable command may be applied one clock
cycle later.
