5. Write Interrupted by Precharge & DQM
A45L9332A Series
PRELIMINARY
(October, 2001, Version 0.1)
22
AMIC Technology, Inc.
Note : 1. To inhibit invalid write, DQM should be issued.
2. 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 dual banks operation.
6. Precharge
7. Auto Precharge
* Note : 1. t
BPL
: Block write data-in to PRE command 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 tRP from this point.
The new read/write command of other active bank can be issued from this point.
At burst read/write with auto precharge,
CAS
interrupt of the same/another bank is illegal.
