Claim 1:
2. The device of claim 1 further comprising:
a third conductive feature extending through the first inter-metal dielectric;
a second bottom electrode over the third conductive feature;
a second magnetic tunnel junction stack over the second bottom electrode;
a second top electrode comprising:
a third conductive layer over the second magnetic tunnel junction stack; and
a fourth conductive layer over the third conductive layer; and

a fourth conductive feature extending through the second inter-metal dielectric, the fourth conductive feature contacting the second top electrode,
wherein the second inter-metal dielectric is over the second top electrode, and
wherein a combined thickness of the third conductive layer and the fourth conductive layer is equal to a combined thickness of the first conductive layer, the dielectric layer, and the second conductive layer.
