CAS Latency
possible CAS latency; 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 t
RP
is met. Note that part
of the row precharge time is 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
PRECHARGE command is that it requires that the com-
mand 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.
Full-page READ bursts can be truncated with the BURST
TERMINATE command, and fixed-length READ bursts
may be truncated with a BURST TERMINATE command,
provided that auto precharge was not activated. The
BURST TERMINATE command should be issued
x
cycles
before the clock edge at which the last desired data
element is valid, where
x
equals the CAS latency minus
one. This is shown in the READ Burst Termination
diagram for each possible CAS latency; data element
n
+
3 is the last desired data element of a longer burst.
