Figure 16. Write to Write - Transition from a burst of 2 to a single write
Data for a fixed-length WRITE burst a full-page WRITE burst
may be followed by, or truncated with, a PRECHARGE com-
mand to the same bank.The PRECHARGE command should
be issued t
after the clock edge at which the last desired
WR
input data element is registered. The auto precharge mode
requires a t
of at least one clock plus time, regardless of
WR
frequency. In addition, when truncating a WRITE burst, the
DQM signal must be used to mask input data for the clock edge
