Abstract
A memory device wherein a diode is serially connected to a programmable resistor and is in electrical communication with a buried digit line. An electrically conductive plug is electrically interposed between the digit line and a strapping layer, thereby creating a double metal scheme wherein the strapping layer is a second metal layer overlying metal wordlines. In a method of a first embodiment the strapping material is electrically connected to the digit line through a planar landing pad overlying the conductive plug. An insulative material is sloped to the planar landing pad in order to provide a surface conducive to the formation of the strapping material.
