Power-Down Command (Active or Precharge)
Note:
Power-down (see Figure 30) 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
synchronously exited when CKE is registered HIGH (in conjunction with a NOP or
DESELECT command). NOP or DESELECT commands must be maintained on the
command bus until

The power-down duration is limited by the refresh requirements of the device.
