General Description

The M66258FP is high speed line memory that uses high performance silicon gate CMOS process technology and adopts the FIFO (First In First Out) structure consisting of 8192 words x 8 bits.

The M66258FP, performing reading and writing operations at different cycles independently and asynchronously, is optimal for buffer memory to be used between equipment of different data processing speeds.
