Abstract:

A system for emulating the memory characteristics of a motor-driven rotating memory having multiple 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 multiplesingle head track. Inputoutput registers are used for each readwrite head that is emulated. An emulation address controller is used to generate all timing and initial addresses. Keywords Patents. R.H.
