GENERAL DESCRIPTION
The K6R1004C1A is a 1,048,576-bit high-speed Static Random
Access Memory organized as 262,144 words by 4 bits. The
K6R1004C1A uses 4 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 SAM-
SUNG s advanced CMOS process and designed for high-
speed circuit technology. It is particularly well suited for use in
high-density
K6R1004C1A is packaged in a 400 mil 32-pin plastic SOJ.
