The power-down state is synchronously exited when CKE is registered high (along with a NOP or Deselect command).

CKE high must be maintained until tCKE has been satisfied. A valid, executable command can be applied with power-down

exit latency, tXP and/or tXPDLL after CKE goes high. Power-down exit latency is defined at AC spec table of this datasheet.
