Abstract:
1. A data memory including memory elements arranged in a three-dimensional pattern defined by rectangular coordinates having x, y and z-directions and with a plurality of parallel planes stacked in the z-direction, the memory further comprising: a plurality of first conductive lines elongated in the z-direction through the plurality of planes and arranged in a two-dimensional rectangular array of rows in the x-direction and columns in the y-direction; a plurality of second conductive lines elongated in the x-direction across individual planes and spaced apart in the y-direction between and separated from the first plurality of conductive lines in the individual planes, wherein the first and second conductive lines cross adjacent each other at a plurality of locations across the individual planes; a plurality of non-volatile re-programmable memory elements individually connected between the first and second conductive lines adjacent the crossings thereof at the plurality of locations; and wherein: a column of first conductive lines in the y-direction is switchably accessed by a corresponding third conductive line pair; individual first conductive lines of even number in the column are switchably coupled to one line of the corresponding third conductive line pair; and individual first conductive lines of odd number in the column are switchably coupled to another line of the corresponding third conductive line pair.
