1. A computer program product for reading a cross point cell array, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code executable by a processing circuit to perform a method comprising:

  • voltage biasing the cross point cell array to determine a state of a target cell on a selected bit line;

    generating a negative magnetic field for a selected write bit line corresponding to the target cell;

    measuring a first current through a selected word line responsive to the negative magnetic field;

    generating a positive magnetic field for the selected write bit line corresponding to the target cell;

    measuring a second current through the selected word line responsive to the positive magnetic field; and

    determining the state of the target cell based on the first current relative to the second current.
