Abstract
The present disclosure 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 top electrode via couples the top electrode to an upper interconnect wire. A first line is tangent to a first outermost sidewall of the top electrode via and a second line is tangent to an opposing second outermost sidewall of the top electrode via. The first line is oriented at a first angle with respect to a horizontal plane that is parallel to an upper surface of the substrate and the second line is oriented at a second angle with respect to the horizontal plane. The second angle is less than the first angle.
