Power-Down Command (Active or Precharge)
Note:
Power-down is entered when CKE is registered LOW. If power-down occurs when all
banks are idle, this mode is referred to as precharge power-down; if power-down occurs
when there is a row active in any bank, this mode is referred to as active power-down.
Entering power-down deactivates the input and output buffers, including CK and CK#.
Exiting power-down requires the device to be at the same voltage as when it entered
power-down and a stable clock.
While in power-down, CKE LOW must be maintained at the inputs of the Mobile DDR
SDRAM, while all other input signals are “Don’t Care.” The power-down state is exited
when CKE is registered HIGH (in conjunction with a NOP or DESELECT command).
NOPs or DESELECT commands must be maintained on the command bus until
satisfied.
