*Note :
1. At full page mode, burst is wrap-around at the end of burst. So auto precharge is impossible.
2. Data-in at the cycle of burst stop command cannot be written into the corresponding memory cell.
It is defined by AC parameter of
t
BDL
(=1CLK).
3. Data-in at the cycle of interrupted by precharge cannot be written into the corresponding memory cell.
It is defined by AC parameter of
t
RDL
(=1CLK).
DQM at write interrupted by precharge command is needed to ensure
t
RDL
of 1CLK.
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.
4. Burst stop is valid only at full page burst length.
