The K6E1004C1B is a 1,048,576-bit high-speed Static Random
Access Memory organized as 262,144 words by 4 bits. The
K6E1004C1B uses 4 common input and output lines and has at
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 K6E1004C1B is packaged
in a 400 mil 28-pin plastic SOJ.
