Terminating a READ Burst
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 com-
mand, 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 Figure 12 for each possible CAS
latency; data element
n
+ 3 is the last desired data ele-
ment of a longer burst.
