Description

The KM68V257E is a 262,144-bit high-speed Static Random Access Memory organized as 32,768 words by 8 bits. The KM68V257E 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 KM68V257E is packaged in a 300mil 28-pin plastic SOJ or TSOP1 forward.
