The GM72V66841CT/CLT 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 to 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 details, refer to the
DQM
control
GM72V66841CT/CLT operating instructions.
