A0 A11
Address
Multiplexed pins for row and column address.
Row address: A0 A11. Column address: A0 A7.
A10 is sampled during a precharge command to
determine if all banks are to be precharged or bank
selected by BS0, BS1.
20, 21 BS0, BS1 Bank Select
Select bank to activate during row address latch time,
or bank to read/write during address latch time.

Disable or enable the command decoder. When
command decoder is disabled, new command is
ignored and previous operation continues.

UDQM
LDQM
Input/output
mask
The output buffer is placed at Hi-Z (with latency of 2)
when DQM is sampled high in read cycle. In write
cycle, sampling DQM high will block the write
operation with zero latency.
38 CLK Clock Inputs System clock used to sample inputs on the rising
edge of clock.
37 CKE Clock Enable
CKE controls the clock activation and deactivation.
When CKE is low, Power Down mode, Suspend
mode, or Self Refresh mode is entered.
