Abstract:
1. A method of storing information to a magnetic memory device, the method comprising; providing a cross-point magnetic memory cell array, the array including a plurality of first conductive lines running parallel to one another in a first direction, a plurality of second conductive lines running parallel to one another in a second direction, the second direction being different from the first direction, and a plurality of magnetic tunnel junctions (MTJ's) disposed between the first conductive lines and the second conductive lines at the intersections of the first conductive lines and the second conductive lines; selecting at least one MTJ to store information in, wherein the other MTJ's are unselected; and storing information in the selected at least one MTJ by running a first current through the first conductive line of the selected at least one MTJ while running a second current through the second conductive line of the selected at least one MTJ and while minimizing a voltage drop across at least one of the MTJ's, wherein the direction of the first current and second current is selected as a function of the physical location of the at least one selected MTJ in the array.
