Note : 1. tRDL: 1CLK

2. tBDL: 1CLK; Last data in to burst stop delay.

Read or write burst stop command is valid at every burst length.

3. Number of valid output data after row precharge or burst stop: 1,2 for CAS latency = 2, 3 respectively.

4. PRE: All banks precharge if necessary.

MRS can be issued only when all banks are in precharged state.
