Description

The M66221 is a mail box that incorporates a complete CMOS shared memory cell of 256 ´ 9-bit configuration using high-performance silicon gate CMOS process technology, and is equipped with two access
ports of A and B.

Access ports A and B of M66221 are equipped with independent addresses CS,WE and OE control pins and I/O pins to allow independent and asynchronous read/write operations from/to shared memory individually. This product also incorporates a port adjustment arbitration function in address contention from both ports.
