Abstract: A non-volatile RAM device is disclosed which utilizes a plurality of ferromagnetic bits (8) each surrounded by a write coil (15) for directing the remnant polarity thereof is disclosed. The direction of magnetic remnance in each bit (8) is dictated by the direction of a current induced into write coil (15). Further, a magneto sensor (9) comprising a magneto resistor (18) coupled to a diode (26) is placed approximate each bit (8). The magneto resistor (18) is coupled to a sense line (20), and receives current at a first point of attachment, and returns current at a second point of attachment. The current passing across magneto resistor (18) is biased in a direction either right or left of the original current flow direction. If current is biased toward the anode end of diode (26) then it is complimentary to the preferred flow direction of diode (26), and flows easily there across.
