Input
Data Input/Output Mask:
DQM0-DQM3 are byte specific, nonpersistent I/O buffer
controls. The I/O buffers are placed in a high-z state when DQM is sampled HIGH.
Input data is masked when DQM is sampled HIGH during a write cycle. Output data
is masked (two-clock latency) when DQM is sampled HIGH during a read cycle.
DQM3 masks DQ31-DQ24, DQM2 masks DQ23-DQ16, DQM1 masks DQ15-DQ8,
and DQM0 masks DQ7-DQ0.

Output
edges of CLK. The I/Os are byte-maskable during Reads and Writes. The DQs also
serve as column/byte mask inputs during Block Writes.
