512K x 8 Bit High-Speed CMOS Static RAM
GENERAL DESCRIPTION
The KM684002A is a 4,194,304-bit high-speed Static Random
Access Memory organized as 524,288 words by 8 bits. The
KM684002A uses 8 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 SAMSUNG
′
s
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 KM684002A is packaged
in a 400mil 36-pin plastic SOJ.
