COMMAND
1. BL = 2. DQM is LOW.
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. An example is shown in Figure 21 on page 33. Data n + 1 is either the
last of a burst of two or the last desired element of a longer burst. The 128Mb SDRAM
uses a pipelined architecture and, therefore, does not require the 2n rule associated with
