SOLID STATE ELECTRONIC EMULATOR OF A MULTIPLE TRACK MOTOR DRIVEN ROTATING MAGNETIC MEMORY

Abstract

A system for emulating the memory characteristics of a motor-driven rotat memory having multiple heads per track and/or single heads per track with odd modular memory lengths. It is intended as a cost effective alternative for replacing magnetic rotating memories. The emulation is accomplished by multiplexing an offset memory address during each bit time. Non-volatile memory arrays translate the memory address to an offset address that is proportional to the odd modular track length of the multiple/single head track. Input/output registers are used for each read/write head that is emulated. An emulation address controller is used to generate all timing and initial addresses.
