KM68257C General Description
The KM68257C is a 262,144-bit high-speed Static Random Access Memory organized as 32,768 words by 8 bits. The KM68257C 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 KM68257C is packaged in a 300 mil 28-pin plastic DIP, SOJ or TSOP1 forward.
