DQM Truth Table

IH L: VIL x VIH or VIL
Write: I
DID is Needed
Read: I
DOD is Needed
The SDRAM can mask input/output data by means of DQM.
During reading, the output buffer is set to Low-Z by setting DQM to Low, enabling data output. On the other
hand, when DQM is set High, the output buffer becomes High-Z, disabling data output.
During writing, data is written by setting DQM to Low. When DQM is set to High, the previous data is held
( the new data is not written). Desired data can be masked during burst read or burst write by setting DQM..
For more details, refer to the DQM control section of the SDRAM operating instructions.
