A WRITE burst may be followed by, or truncated with a PRECHARGE command to the same bank, provided that
Auto Precharge was not activated. This is shown in
The PRECHARGE command should be issued t
the WRITE burst was registered. Additionally, when truncating a WRITE burst, DQM must be pulled to mask input
data presented during t
subsequent ACTIVE command to the same bank cannot be issued until t
In the case of a WRITE being executed to completion, a PRECHARGE command issued at the optimum time (as
described above) provides the same operation that would result from the same WRITE burst with Auto Precharge
enabled. The disadvantage of the PRECHARGE command is that it requires that the command and address
busses be available at the appropriate time to issue the command. The advantage of the PRECHARGE command
is that it can be used to truncate bursts.
