Page Read & Write Cycle at Same Bank @ Burst Length = 4
Note : 1. To Write data before burst read ends. DQM should be asserted three cycle prior to write command to avoid bus
contention.
2. Row precharge will interrupt writing. Last data input , t
RDL
before row precharge , will be written.
3. 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.
