GENERAL DESCRIPTION

The KM681002B is a 1,048,576-bit high-speed Static Random Access Memory organized as 131,072 words by 8 bits. The KM681002B 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 KM681002B is packaged in a 400mil 32-pin plastic SOJ or TSOP2 forward.
