the clock edge at which the last desired data element is
valid, where x equals the CAS latency minus one. This is
possible CAS latency;data element n + 3 is the last desired
data element of a longer burst.

3 is either the last of a burst of four or the last desired of
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 disadvantage of the PRE-
CHARGE 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
TERMINATE command, and fixed-length READ bursts
provided that auto precharge was not activated.The BURST
TERMINATE command should be issued x cycles before
