256K x 16 Bit High-Speed CMOS Static RAM
The KM6164002A is a 4,194,304-bit high-speed Static Ran-
dom Access Memory organized as 262,144 words by 16 bits.
The KM6164002A 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 fabri-
cated 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 KM6164002A is packaged in a 400mil 44-pin plastic SOJ
or TSOP(II) forward.
