CMOS SRAM
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.
