*Note :
1. t
RDL
: Last data in to row precharge delay
2. Number of valid output data after row precharge : 0, 1, 2 for CAS Latency =1, 2, 3 respectively.
3. The row active command of the precharge bank can be issued after t
RP
from this point.
The new read/write command of the other activated bank can be issued from this point.
At burst read/write with auto precharge, CAS interrupt of the same/other bank is illegal.
