GENERAL DESCRIPTION
The KM6161002B is a 1,048,576-bit high-speed Static Random
Access Memory organized as 65,536 words by 16 bits. The
KM6161002B uses 16 common input and output lines and has
at 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
KM6161002B is packaged in a 400mil 44-pin plastic SOJ or
TSOP2 forward.
