The M5M54R01AJ is a family of 4194304-word by 1-bit
static RAMs, fabricated with the high performance CMOS
silicon gate process and designed for high speed
application.
These devices operate on a single 3.3V supply, and are
directly TTL compatible. They include a power down
feature as well.

The operation mode of the M5M54R01AJ 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
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.
The RAM works with an organization of 4194304-word by 1bit,
when B1/B4 is low of floating. And an organization of 1048576-word
by 4bit is also obtained for reducing the test time,when B1/B4 is
high. The pin configuration and function is as same as
M5M54R04AJ.
