WRITE Command
WRITE Burst
Note:
An example is shown in Figure 20 on page 31. Data n + 1 is either the last of a burst of two
or the last desired of a longer burst. The 64Mb SDRAM uses a pipelined architecture and
therefore does not require the 2n rule associated with a prefetch architecture. A WRITE
command can be initiated on any clock cycle following a previous WRITE command.
Full-speed random write accesses within a page can be performed to the same bank, as
shown in Figure 21 on page 32, or each subsequent WRITE may be performed to a
different bank.
