being accessed is precharged at the completion of the burst. For the generic WRITE commands
used in the following illustrations, auto precharge is disabled.
During WRITE bursts, the first valid data-in element will be registered coincident with the
WRITE command. Subsequent data elements will be registered on each successive positive
clock edge. Upon completion of a fixed-length burst, assuming no other commands have been
initiated, the DQs will remain High-Z, and any additional input data will be ignored. A full-page
burst will continue until terminated. (At the end of the page, it will wrap to column 0 and
continue.)
Data for any WRITE burst may be truncated with a subsequent WRITE command, and data for a
fixed length WRITE burst may be immediately followed by data for a WRITE command. The
new WRITE command can be issued on any clock following the previous WRITE command,
and the data provided coincident with the new command applies to the new command (see
Figures 29, 30, 31, and 32).
