Abstract
A memory device includes a memory cell comprising a bottom electrode, a top electrode, and a dielectric layer interposed between the bottom electrode and the top electrode. The bottom electrode has a first width W. The top electrode has a top surface that has a second width Wbetween two edges of the top surface. The memory cell has a first height Hextending from a lower surface of the bottom electrode to the top surface of the top electrode. The memory device further includes a top contact wire coupled to the top electrode. The top contact wire has a top surface that has a third width W, a second height Hat a location between two adjacent memory cells, and a third height Hextending between the top surface of the top contact wire and the insulating layer, where W>W>Wand H>H>H
