WRITE-to-PRECHARGE
Note:
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.
Fixed-length or full-page WRITE bursts can be truncated with the BURST TERMINATE
command. When truncating a WRITE burst, the input data applied coincident with the
BURST TERMINATE command will be ignored. The last data written (provided that
DQM is LOW at that time) will be the input data applied one clock previous to the
BURST TERMINATE command. This is shown in Figure 23 on page 32, where data n is
the last desired data element of a longer burst.

DQM could remain LOW in this example if the WRITE burst is a fixed length of two.
