WRITE-to-PRECHARGE
Terminating a WRITE Burst

Notes:
COMMAND
COMMAND
1. DQM could remain LOW in this example if the WRITE burst is a fixed length of two.
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 22, where data n is the last
desired data element of a longer burst.
