FIG. 12 WRITE INTERRUPTED BY PRECHARGE COMMAND & WRITE
BURST STOP CYCLE @ BURST LENGTH=FULL PAGE
NOTES:
1. At full page mode, burst is end at the end of burst. So auto precharge is possible.
2. Data-in at the cycle of interrupted by precharge cannnot be written into the corresponding memory cell. It is defined by AC parameter of
tRDL. DQM at write interrupted by precharge command is needed to prevent invalid write. DQM should mask invalid input data on
precharge command cycle when asserting precharge before end of burst. Input data after Row precharge cycle will be masked internally.
3. Burst stop is valid at every burst length.
