Product Preview
256K x 4 Bit Static Random
Access Memory
The MCM6229BB is a 1,048,576 bit static random access memory organized
as 262,144 words of 4 bits. Static design eliminates the need for external clocks
or timing strobes while CMOS circuitry reduces power consumption and provides
for greater reliability.
The MCM6229BB is equipped with both chip enable (E) and output enable (G)
pins, allowing for greater system flexibility and eliminating bus contention problems.
The MCM6229BB is available in 300 mil and 400 mil, 28 lead surface–mount
SOJ packages.
Single 5 V
