WRITE-to-WRITE
Random WRITE Cycles
Notes:
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 22 on page 33, or each subsequent
WRITE may be performed to a different bank.
Data for any WRITE burst may be truncated with a subsequent READ command, and
data for a fixed-length WRITE burst may be immediately followed by a READ command.
After the READ command is registered, the data inputs will be ignored, and writes will
not be executed. An example is shown in Figure 23 on page 34. Data n + 1 is either the
last of a burst of two or the last desired element of a longer burst.
COMMAND
1. DQM is LOW. Each WRITE command may be to any bank.
