This datasheet also covers the KM68257C variant, as both devices belong to the same 32kx8 bit high speed static ram family and are provided as variant models within a single manufacturer datasheet.
General Description
The KM68257C is a 262,144-bit high-speed Static Random Access Memory organized as 32,768 words by 8 bits.
The KM68257C uses 8 common input and output lines and has an output enable pin which operates faster than address access time at read cycle.
