FUNCTION
The operation mode of the M5M5V108C series are determined by
a combination of the device control inputs S
1
,S
2
,W and OE.
Each mode is summarized in the function table.
A write cycle is executed whenever the low level W overlaps with
the low level S
1
and the high level S
2
. The address must be set up
before the write cycle and must be stable during the entire cycle.
The data is latched into a cell on the trailing edge of W,S
1
or S
2
,
whichever occurs first,requiring the set-up and hold time relative to
these edge to be maintained. The output enable input OE directly
controls the output stage. Setting the OE at a high level, the output
stage is in a high-impedance state, and the data bus contention
problem in the write cycle is eliminated.
A read cycle is executed by setting W at a high level and OE at a
low level while S
1
and S
2
are in an active state(S
1
=L,S
2
=H).
BLOCK DIAGRAM
When setting S
1
at a high level or S
2
at a low level, the chip are in
a non-selectable mode in which both reading and writing are
disabled. In this mode, the output stage is in a high- impedance
state, allowing OR-tie with other chips and memory expansion by
S
1
and S
2
. The power supply current is reduced as low as the
stand-by current which is specified as I
CC3
or I
CC4
, and the memory
data can be held at +2V power supply, enabling battery back-up
operation during power failure or power-down operation in the non-
selected mode.
