The KM6164002 is a 4,194,304-bit high-speed Static Random
Access Memory organized as 262,144 words by 16 bits. The
KM6164002 uses 16 common input and output lines and has an
output enable pin which operates faster than address access
time at read cycle. Also it allows that lower and upper byte
access by data byte control (UB, LB). The device is fabricated
using SAMSUNG's advanced CMOS process and designed for
high-speed circuit technology. It is particularly well suited for use
