Patent ID: 7020012

Claim:
A cross point array comprising: a first layer of conductive array lines, the conductive array lines being arranged so that they do not come into direct contact with each other; and a second layer of conductive array lines, the conductive array lines being arranged so that they do not come into direct contact with either each other or any of the conductive array lines of the first layer; wherein one conductive array line from the first layer of conductive array lines and one conductive array line from the second layer of conductive array lines define a unique pair of conductive array lines, across which a read current is indicative of stored data value, wherein applying a first select voltage to the one conductive array line from the first layer of conductive array lines and a second select voltage to the one conductive array line from the second layer of conductive array lines stores a first data value; and wherein an unselect voltage can be applied to the unselected conductive array lines in the first and second layers, the unselect voltage being approximately equal to the average of the first select voltage and the second select voltage.
