DQMU/DQML Control
The DQMU and DQML mask the upper and lower bytes of the DQ data respectively. The timing of DQMU/
DQML is different during reading and writing.
Reading: When data is read, the output buffer can be controlled by DQMU/DQML. By setting DQMU/DQML
to Low, the output buffer becomes Low-Z, enabling data output. By setting DQMU/DQML to High, the output
buffer becomes High-Z and the corresponding data is not output. However, internal reading operations
continue. The latency of DQMU/DQML during reading is 2 clocks.
Writing: Input data can be masked by DQMU/DQML. By setting DQMU/DQML to Low, data can be written.
In addition, when DQMU/DQML is set to High, the corresponding data is not written, and previous data is
held. The latency of DQMU/DQML during writing is 0 clock.
