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.
