COMMAND
COMMAND
The burst read/single write mode is entered by programming the write burst mode bit
(M9) in the mode register to a logic 1. In this mode, all WRITE commands result in the
access of a single column location (burst of one), regardless of the programmed burst
length. READ commands access columns according to the programmed burst length
and sequence, just as in the normal mode of operation (M9 = 0).
