GENERAL DESCRIPTION
The KM616V4002C is a 4,194,304-bit high-speed Static Ran-
dom Access Memory organized as 262,144 words by 16 bits.
The KM616V4002C 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 in high-density high-speed system applications.
The KM616V4002C is packaged in a 400mil 44-pin plastic SOJ
or TSOP(II) forward or 48 Fine pitch BGA.
