: Don't care
*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.
4. For -55/60/70/80/10, tRDL=1CLK product can be supported within restricted amounts and it will be distinguished by bucket code
"NV". From the next generation, tRDL will be only 2CLK for every clock frequency
