DESCRIPTION
The M5M532R16 is a family of 32768-word by 16-bit
static RAMs, fabricated with the high performance CMOS
process and designed for high speed application. These
devices operate on a single 5V supply, and are directly
TTL compatible.
They include a power down feature as well. In write
and read cycles, the lower and upper bytes are able
to be controled either togethe or separately by /LB
and /UB.

FUNCTION
The operation mode of the M5M532R16 is determined
by a combination of the device control inputs /S, /W,
/OE, /LB, and /UB. Each mode is summarized in the
function table.
A write cycle is executed whenever the low level /W
overlaps with low level /LB and/or low level /UB and low
level /S. The address must be set-up before write cycle
and must be stable during the entire cycle. upper-Byte are in a non-selectable mode.
The data is latched into a cell on the traling edge of
/W, /LB, /UB 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 /LB and/or /UB and /S are
in an active state. (/LB and/or /UB=L, /S=L)
When setting /LB at a high level and other pins are in
an active state, upper-Byte are in a selectable mode
in which both reading and writing are enable, and
lower-Byte are in a non-selectable mode. And when
setting /UB at a high level and other pins are in an
active state, lower-Byte are in a selectable mode in
which both reading and writing are enable, and
When setting /LB and /UB at a high level or /S at high
level, the chip is 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 /LB, /UB and /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.
