This paper will be concerned with a discussion of the memory cellsfrom both a practical and theoretical viewpoint. It will be shown howthese cells can be fabricated into memory arrays. One such configurationconsists solely of vertical copper wires and horizontal magnetic results of the switching behavior of many magnetic ma-terials when operated in the twisted manner will be given.
