Devices and methods for forming a device are disclosed. A substrate having circuit component formed on a substrate surface is provided. Back end of line processing is performed to form an upper inter level dielectric (ILD) layer over the substrate. The upper ILD layer includes a plurality of ILD levels. A pair of magnetic tunneling junction (MTJ) stacks is formed in between adjacent ILD levels of the upper ILD layer. Each of the MTJ stack includes a fixed layer, a tunneling barrier layer and a free layer. The fixed layer has a first width. The tunneling barrier layer is formed on the fixed layer. The free layer is formed on the tunneling barrier layer. The free layer has a second width. The first width is wider than the second width.
