Abstract
A three port memory device has two serial ports and a random access memory port. The random access memory port is addressed to a random access memory in a conventional manner, using RAS and CAS address signals. Data may also be supplied and retrieved through two serial ports to a pair of serial access memories for transfer between the serial ports and the random access memory. This configuration permits formatted data to be simultaneously assessed through the two serial ports, while the random access memory port is being accessed.
