The Data Input/Output mask places the DQ buffers in a
high impedance state when sampled high. In Read mode,
DQM has a latency of two clock cycles and controls the
output buffers like an output enable. In Write mode, DQM
has a latency of zero and operates as a word mask by
allowing input data to be written if it is low but blocks the
write operation if DQM is high.
One DQM input it present in x4 and x8 SDRAMs, LDQM
and UDQM controls the lower and upper bytes in x16
SDRAMs.
