A fixed-length READ burst may be followed by, or truncated with, a PRECHARGE
command to the same bank (provided that auto precharge was not activated), and a full-
page burst may be truncated with a PRECHARGE command to the same bank. The
PRECHARGE command should be issued x cycles before the clock edge at which the last
desired data element is valid, where x = CL - 1. This is shown in Figure 18 on page 33 for
each possible CL; data element n + 3 is either the last of a burst of four or the last desired
of a longer burst. Following the PRECHARGE command, a subsequent command to the
same bank cannot be issued until
hidden during the access of the last data element(s).
In the case of a fixed-length burst 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 fixed-length burst with auto precharge. The disadvan-
tage 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 fixed-length or full-page bursts.
