The operation mode of the M5M5V4R08J is determined by a
combination of the device control inputs S, 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. 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 or S,
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
FUNCTION TABLE
contention problem in the write cycle is eliminated.
A read cycle is excuted by setting W at a high level and OE at a
low level while S are in an active state (S=L).
When setting S at high level, the chip is in a non-selectable
mode in which both reading and writing are disable. In this mode,
the output stage is in a high-impedance state, allowing OR-tie
with other chips and memory expansion by S.
Signal-S controls the power-down feature. When S goes high,
power dissapation is reduced extremely. The access time from S is
equivalent to the address access time.
