Abstract
In some embodiments, the present disclosure relates to an integrated chip (IC), including a bottom electrode overlying an interconnect structure disposed within a lower inter-level dielectric (ILD) layer, a top electrode over the bottom electrode, a data storage structure between the top electrode from the bottom electrode, a conductive barrier layer directly overlying the interconnect structure, and a bottom electrode via (BEVA) vertically separating and contacting a bottom surface of the bottom electrode and a top surface of the conductive barrier layer. A maximum width of the BEVA is less than a width of the data storage structure.
