Motorola, Inc. 1994
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 pro-
vides reduced system power requirements without degrading access time per-
formance.
The MCM6227B is available in 300 mil and 400 mil, 28–lead surface–mount
SOJ packages.
Single 5 V
