.
In the case of a READ 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 READ burst with AUTO
PRECHARGE enabled. The disadvantage of the PRECHARGE command is that it requires that the
command and address buses 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.
