REV. 1.1 Nov. '99

*Note :
1. To prevent bus contention, DQM should be issued which makes at least one gap between data in and data out.
2. To inhibit invalid write, DQM should be issued.
3. This precharge command and burst write command should be of the same bank, otherwise it is not precharge
interrupt but only another bank precharge of four banks operation.
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.

*Note :
1. t
RDL
: Last data in to row precharge delay
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
RP
from this point.
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.
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
