Write With Auto-Precharge
The write with auto-precharge command first executes a
burst write operation and then puts the selected bank in the
precharged state automatically. After the precharge
completes the bank goes to the idle state. Thus this
command performs a write command and a precharge
command in a single operation.
During this operation, the delay period (t
DAL
) between the
last burst data input and the completion of the precharge
operation differs depending on the
CAS
latency setting.
The delay (t
DAL
) is t
RP
plus one CLK period. That is, the
precharge operation starts one clock period after the last
burst data input.
Therefore, the selected bank can be made active after a
delay of t
DAL
.
The selected bank must be set to the active state before
executing this command.
The auto-precharge function is invalid if the burst length is
set to full page.
