Claim Text:
1. A three-dimensional array of read/write elements comprising: a plurality of horizontal line stacks, each horizontal line stack comprising a plurality of electrically-conductive horizontal lines that extend in a first direction and are vertically separated from each other by insulating material, individual stacks separated from adjacent stacks in a second direction that is perpendicular to the first direction; a plurality of cylinders of read/write material located between a first horizontal line stack and a second horizontal line stack so that each cylinder of the plurality of cylinders is in electrical contact with horizontal lines of the first and second horizontal line stacks; a plurality of vertical lines, each vertical line extending through a corresponding cylinder of read/write material to form read/write elements between the vertical line and horizontal lines of the first and second horizontal line stacks; wherein the electrically-conductive horizontal lines of the first and second horizontal line stacks include sheet electrodes that extend towards the vertical lines, a sheet electrode having a vertical thickness that is less than the total vertical thickness of a horizontal line; and wherein the sheet electrode extends horizontally into a cylinder of read/write material.
