This is a 128k x 8 bit high-performance cmos static ram with fast access time, low power consumption, high reliability, low cost and small size.
The Samsung KM681002B and KM681002BI are 128K x 8-bit high-speed static random access memories (SRAM) organized as 131,072 words by 8 bits. These devices utilize 8 common input and output lines and feature an output enable pin designed for faster read cycles compared to address access times. Fabricated using Samsung's advanced CMOS process, they are suitable for high-density, high-speed system applications and are available in 32-pin SOJ or TSOP2 packages.
