Terminating a WRITE Burst
PRECHARGE Command
Note:
Power-down occurs if CKE is registered LOW coincident with a NOP or COMMAND
INHIBIT when no accesses are in progress. 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, excluding CKE, for maximum
power savings while in standby. The device may not remain in the power-down state
longer than the refresh period (64ms) since no refresh operations are performed in this
mode.
The power-down state is exited by registering a NOP or COMMAND INHIBIT and CKE
HIGH at the desired clock edge (meeting
