Motorola, Inc. 1994
1M x 1 Bit Static Random
Access Memory
The MCM6227A is a 1,048,576 bit static random–access memory organized
as 1,048,576 words of 1 bit, fabricated using high–performance silicon–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.
The MCM6227A is equipped with a chip enable (E) pin. In less than a cycle time
after E goes high, the part enters a low–power standby mode, remaining in that
state until E goes low again.
The MCM6227A is available in 400 mil, 28–lead surface–mount SOJ pack-
ages.
