128K x 8 Bit High-Speed CMOS Static RAM
GENERAL DESCRIPTION
The KM681002A is a 1,048,576-bit high-speed Static Random
Access Memory organized as 131,072 words by 8 bits. The
KM681002A 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 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 KM681002A is packaged
in a 400mil 32-pin plastic SOJ or TSOP2 forward.
