write cycle
Precharge command
A Precharge command can be used to interrupt burst read/write operation during the read cycle. During RD, burst read is
terminated and o/p goes to High Z after CAS latency. The same bank can be activated after t
RP
. During write, burst write
operation is terminated immediately. Data written two cycles prior to the precharge command will be correctly stored. Set
DQM high one cycle before Precharge command and hold it high until Precharge command to mask and avoid writing invalid
data.
