1. t
RDL
: 1 CLK, Last Data in to Row Precharge.
2. t
BDL
: 1 CLK, Last Data in to Burst Stop Delay.
3. Number of valid output data after Row precharge or burst stop : 1, 2 for CAS latency= 2, 3 respectiviely.
4. PRE : Both banks precharge if necessary.
MRS can be issued only at all bank precharge state.
