Data from any READ burst may be truncated with a BURST TERMINATE command, as
shown in Figure 31 on page 58. The BURST TERMINATE latency is equal to the CL, that
is, the BURST TERMINATE command should be issued x cycles after the READ
command where x equals the number of desired data element pairs (pairs are required
by the 2n-prefetch architecture).
Data from any READ burst must be completed or truncated before a subsequent WRITE
command can be issued. If truncation is necessary, the BURST TERMINATE command
must be used, as shown in Figure 32 on page 59. The

defined in the section on WRITEs.) A READ burst may be followed by, or truncated with,
a PRECHARGE command to the same bank provided that auto precharge was not acti-
vated.
The PRECHARGE command should be issued x cycles after the READ command, where
x equals the number of desired data element pairs (pairs are required by the 2n-prefetch
architecture). This is shown in Figure 33 on page 60. Following the PRECHARGE
command, a subsequent command to the same bank cannot be issued until both
and
last data elements.
