1048576-BIT(131072-WORD BY 8-BIT)CMOS STATIC RAM
DESCRIPTION
The M5M51008BFP,VP,RV,KV,KR are a 1048576-bit CMOS
static RAM organized as 131072 word by 8-bit which are
fabricated using high-performance triple polysilicon CMOS
technology. The use of resistive load NMOS cells and CMOS
periphery result in a high density and low power static RAM.
They are low standby current and low operation current and ideal
for the battery back-up application.
The M5M51008BVP,RV,KV,KR are packaged in a 32-pin thin
small outline package which is a high reliability and high density
surface mount device(SMD).Two types of devices are available.
VP,KV(normal lead bend type package),RV,KR(reverse lead bend
type package). Using both types of devices, it becomes very easy
to design a printed circuit board.

FUNCTION
The operation mode of the M5M51008B series are determined by
a combination of the device control inputs S1,S2,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 S1 and the high level S2. 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,S1 or
S2,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 S1 and S2 are in an active state(S1=L,S2=H).
When setting S1 at a high level or S2 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
S1 and S2. The power supply current is reduced as low as the
stand-by current which is specified as ICC3 or ICC4, 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.
