Abstract:
The ferromagnetic memory cell, comprising:a) a bit, having: 1) a central point located approximately at a center of the bit; 2) a outside surface, defining an outer periphery of the bit located furthest from the central point; and 3) a mass of ferromagnetic material located between the central point and the outside surface; b) a write line, positioned around at least a portion of the outside surface sufficient to direct the polarity of the bit; c) a sample drive line, positioned separate from the write line but proximate the bit to transmit an electric pulse that will increase the directed polarity of the bit; d) a sense line, positioned proximate the bit sufficient to detect the increased directed polarity of the bit; wherein a wave is induced into the sense line as a result of the increased directed polarity; wherein the wave induced into the sense line is a positive wave and represents a binary â€œ1â€ ; and wherein the sense line and the sample drive line are on opposite ends of the bit.
