Abstract: An apparatus including a pillar located over a substrate and having at least one sloped surface oriented at an acute angle relative to the substrate. The apparatus also includes an MRAM stack substantially conforming to the sloped surface, the MRAM stack thereby also oriented at the acute angle relative to the substrate. The MRAM stack may comprise a plurality of substantially planar, parallel layers each oriented at an acute angle relative to the substrate.
