GENERAL DESCRIPTION
The KM644002C is a 4,194,304-bit high-speed Static Random
Access Memory organized as 1,048,576 words by 4 bits. The
KM644002C uses 4 common input and output lines and has an
output enable pin which operates faster than address access
time at read cycle. The device is fabricated using SAMSUNGs
advanced CMOS process and designed for high-speed circuit
technology. It is particularly well suited for use in high-density
high-speed system applications. The KM644002C is packaged
in a 400 mil 32-pin plastic SOJ.
