The KM68V1002A is a 1,048,576-bit high-speed Static Ran-
dom Access Memory organized as 131,072 words by 8 bits.
The KM68V1002A 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 Sam-
sung
′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 KM68V1002A is
packaged in a 400mil 32-pin plastic SOJ or TSOP2 forward.
