Abstract
The present disclosure, in some embodiments, relates to an integrated chip. The integrated chip includes a memory device surrounded by a dielectric structure disposed over a substrate. The memory device includes a data storage structure disposed between a bottom electrode and a top electrode. A bottom electrode via couples the bottom electrode to a lower interconnect. A top electrode via couples the top electrode to an upper interconnect. A bottommost surface of the top electrode via is directly over the top electrode and has a first width that is smaller than a second width of a bottommost surface of the bottom electrode via.
