ORDERING INFORMATION
GENERAL DESCRIPTION
The K6R4008V1B is a 4,194,304-bit high-speed Static Random
Access Memory organized as 524,288 words by 8 bits. The
K6R4008V1B 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 SAM-
SUNG s advanced CMOS process and designed for high-
speed circuit technology. It is particularly well suited for use in
high-density
K6R4008V1B is packaged in a 400 mil 36-pin plastic SOJ or
TSOP(II) forward or 44-pin plastic TSOP(II) forward.
