Patent attributes
The present disclosure relates to a memory device. The memory device includes an access device arranged on or within a substrate and coupled to a word-line and a source line. A plurality of lower interconnects are disposed within a lower dielectric structure over the substrate. A first electrode is coupled to the plurality of lower interconnects. The plurality of lower interconnects couple the access device to the first electrode. A second electrode is over the first electrode. One or more upper interconnects are disposed within an upper dielectric structure laterally surrounding the second electrode. The one or more upper interconnects couple the second electrode to a bit-line. A data storage structure is disposed between the first electrode and the second electrode. The data storage structure includes one or more metals having non-zero concentrations that change as a distance from the substrate varies.
