Write Cycle Interruption Using the
Precharge Command
A write cycle can be interrupted by the execution of the
precharge command before that cycle completes. The
delay time (t
WDL
) from the precharge command to the point
where burst input is invalid, i.e., the point where input data
is no longer written to device internal memory is zero clock
cycles regardless of the
CAS
.
To inhibit invalid write, the DQM signal must be asserted
HIGH with the precharge command.
This precharge command and burst write command must
be of the same bank, otherwise it is not precharge interrupt
but only another bank precharge of dual bank operation.
Inversely, to write all the burst data to the device, the
precharge command must be executed after the write
data recovery period (t
DPL
) has elapsed. Therefore, the
precharge command must be executed on one clock
cycle that follows the input of the last burst data item.
