FUNCTION
Multiplexed pins for row and column address.
Row address: A0−A10. Column address: A0−A7.
Address
A10 is sampled during a precharge command to
determine if all banks are to be precharged or
bank selected by BS0, BS1.
Select bank to activate during row address latch
Bank Select time, or bank to read/write during address latch
time.
Data
Multiplexed pins for data output and input.
Input/ Output
Disable or enable the command decoder. When
Chip Select command decoder is disabled, new command is
ignored and previous operation continues.

The output buffer is placed at Hi-Z (with latency
Input/Output of 2) when DQM is sampled high in read cycle.
Mask In write cycle, sampling DQM high will block the
write operation with zero latency.
