1M x 32 Bit Fast Static RAM Module

The MCM321024 is an 32M bit static random access memory module organized as 1,048,576 words of 32 bits. The module is a 72–lead single in–line memory module (SIMM) consisting of eight MCM6249 fast static RAMs packaged in 32–lead SOJ packages and mounted on a printed circuit board along with sixteen decoupling capacitors.

The MCM6249 is a high performance CMOS fast static RAM organized as 1,048,576 words of 4 bits. Static design eliminates the need for external clocks or timing strobes, while CMOS circuitry reduces power consumption and provides for greater reliability.
