Description

The MCM32515 is a 16M bit static random access memory module organized as 524,288 words of 32 bits. The module is offered in a 72lead single inline memory module (SIMM). Four MCM6246 fast static RAMs, packaged in 36lead
SOJ packages are mounted on a printed circuit board along with eight decoupling capacitors.

The MCM6246 is a highperformance CMOS fast static RAM organized as 524,288 words of 8 bits. Static design eliminates the need for external clocks or timing strobes, while CMOS circuitry reduces power consumption and provides for greater reliability.

The MCM32515 is equipped with output enable (G) 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.
