128K x 32 Bit
Fast Static RAM Module
The MCM32128 is a 4M bit static random access memory module organized
as 131,072 words of 32 bits. The module is offered in either a 64-lead zig-zag
in-line package (ZIP) or a 64-lead single in-line memory module (SIMM). Four
MCM6226A fast static RAMs, packaged in 32-lead SOJ packages are mounted
on a printed circuit board along with four decoupling capacitors.
The MCM6226A is a high-performance CMOS fast static RAM organized as
131,072 words of 8 bits, fabricated using high-performance silicon-gate CMOS
technology. Static design eliminates the need for external clocks or timing
strobes, while CMOS cirCUitry reduces power consumption and provides for
greater reliability.
The MCM32128 is equipped with output enable (<3) and four separate byte
enable (E1 - E4) inputs, allowing for greater system flexibility. The G input, when
high, will force the outputs to high impedance. Ex high will do the same for
byte x.
