Abstract
A nonvolatile ferromagnetic RAM device which is capable of reading the data stored in each magnet quickly and efficiently utilizing a minimal number of components. Specifically there is a nonvolatile ferromagnetic RAM which is capable of reading the data stored in each magnetic bit. The ferromagnetic memory cell, comprising of a base (,) that is oriented in a horizontal plane. There is also a bit (,), made of a ferromagnetic material, having: a height that is oriented perpendicular to the horizontal plane of the base, and a polarity that can be directed along the height. Additionally, there is a sense line (,), positioned proximate the bit (,) sufficient to detect the directed polarity of the bit; and a write line (,), positioned proximate the bit sufficient to direct the polarity of the bit. Additionally, there is a detector, coupled to the sense line; and a sample drive line (,), positioned proximate the bit (,) to transmit an electric pulse that will increase the directed polarity of the bit sufficient to induce a wave into the sense line that can be detected by the detector.
