SEMICONDUCTOR TECHNICAL DATA
MCM6264C
8K x 8 Bit Fast Static RAM
TheMCM6264CisfabricatedusingMotorola’shigh–performancesilicon–gate
CMOS technology. Static design eliminates the need for external clocks or timing
strobes, while CMOS circuitry reduces power consumption and provides for
greater reliability.
This device meets JEDEC standards for functionality and pinout, and is avail-
able in plastic dual–in–line and plastic small–outline J–leaded packages.
