Advance Information
1M x 8 Bit
Fast Static RAM Module
The MCM8A10 is an 8M bit static random access memory module organized
as 1,048,576 words of 8 bits. The module is offered in a 72–lead single in–line
memory module (SIMM). Eight MCM6227B fast static RAMs, packaged in
28–lead SOJ packages are mounted on a printed circuit board along with eight
decoupling capacitors.
The MCM6227B is organized as 1,048,576 words of 1 bit. Static design elimi-
nates the need for external clocks or timing strobes, while CMOS circuitry re-
duces power consumption and provides for greater reliability.
The MCM8A10 is equipped with a chip enable (E
)
and eight separate write
enable (W0 – W7) inputs, allowing for greater system flexibility.
