Abstract
Some embodiments relate to an integrated chip having a memory cell overlying a substrate and comprising a top electrode. A top electrode via overlies the top electrode. A width of an upper surface of the top electrode via is greater than a width of an upper surface of the top electrode. A conductive via overlies the top electrode via. A width of an upper surface of the conductive via is greater than the width of the upper surface of the top electrode via.
