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 eliminates the need for external clocks or timing strobes, while CMOS circuitry reduces 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.
