GENERAL DESCRIPTION
The KM68257E is a 262,144-bit high-speed Static Random
Access Memory organized as 32,768 words by 8 bits. The
KM68257E 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 SAMSUNGs
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 KM68257E is packaged in
a 300mil 28-pin plastic SOJ or TSOP1 forward.
