1. t
2. Number of valid output data after row precharge: 1, 2 for CAS Latency = 2, 3 respectively.
3. The row active command of the precharge bank can be issued after t
1 ) N o r m a l W r i t e ( B L = 4 )
The new read/write command of other activated bank can be issued from this point.
At burst read/write with auto precharge, CAS interrupt of the same/another bank is illegal.
