Abstract:
1. An apparatus comprising: a cross point army including a first plurality of conductive army lines and a second plurality of conductive array lines arranged such that each conductive array line from the first plurality of conductive array lines crosses all the conductive array lines from the second plurality of conductive army lines and each conductive array line from the second plurality of conductive array lines crosses all the conductive array lines from the first plurality of conductive array lines; circuitry in electrical contact with the conductive array lines that provides a reference voltage to the conductive array lines when activated; wherein a unique pair of conductive array lines can be selected by applying a first select voltage to a conductive array line from the first plurality of conductive array lines and applying a second select voltage to a conductive array line from the second plurality of conductive array lines, whereby a voltage drop approximately equal to the difference between the first select voltage and the second select voltage occurs across the selected pair of conductive array lines and not across any unselected pairs of conductive array lines.
