GENERAL DESCRIPTION
The K6R1008C1A is a 1,048,576-bit high-speed Static Random
Access Memory organized as 131,072 words by 8 bits. The
K6R1008C1A 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 K6R1008C1A is packaged
in a 400mil 32-pin plastic SOJ or TSOP2 forward.
