WRITE Command
WRITE bursts are initiated with a WRITE command, as shown in Figure 20.
The starting column and bank addresses are provided with the WRITE command, and
auto precharge either is enabled or disabled for that access. If auto precharge is enabled,
the row being accessed is precharged at the completion of the burst. For the 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 DQ will remain High-Z, and any additional input
data will be ignored (see Figure 21 on page 36). A full-page burst will continue until
terminated. (At the end of the page, it will wrap to column 0 and continue.)
x16: A0–A8
x32: A0–A7
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 36. Data n + 1 is either the
last of a burst of two or the last desired of a longer burst. The 128Mb SDRAM uses a pipe-
lined 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 22 on page 36, or each subsequent WRITE may be
performed to a different bank.
