1M x 1 Bit Static Random Access Memory

The MCM6227B is a 1,048,576 bit static random–access memory 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 MCM6227B is each equipped with a chip enable (E) pin. This feature provides reduced system power requirements without degrading access time performance.

The MCM6227B is available in 300 mil and 400 mil, 28–lead surface–mount SOJ packages.
