FUNCTION
The operation mode of the M5M51008B 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).

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.
