WRITE Burst (CAS Latency = 3)
Data for any WRITE burst may be concatenated with or truncated with a subsequent WRITE command. In either
case, a continuous flow of input data can be maintained. A WRITE command can be issued on any positive edge
of clock following the previous WRITE command. The first data element from the new burst is applied after either
the last element of a completed burst (
Figure 30
) or the last desired data element of a longer burst which is being
truncated (
Figure 31
). The new WRITE command should be issued x cycles after the first WRITE command,
where x equals the number of desired data elements.
Please note that truncation of a WRITE burst by a subsequent READ or WRITE is only possible when both
commands are issued to the same chip of this stacked configuration.
