Classification: CPC G  H | IPC G  H

Claim 19:
20. A non-volatile memory structure comprising:
a magnetoresistive random access memory (MRAM) array comprising a plurality of MRAM devices, wherein each MRAM device of the plurality of MRAM devices comprises a bottom electrode, a magnetic tunnel junction (MTJ) pillar, and a top electrode, and each MRAM device is located between a first electrically conductiive structure and a second electrically conductive structure;
a bottom magnetic shield containing-material layer located beneath each MTJ pillar, but above the first electrically conductive structure; and
a top magnetic shield containing-material layer located above each MRAM device, wherein the top magnetic shield containing-material layer is positioned laterally adjacent to, but not above or below, the second electrically conductive structure, wherein the bottom magnetic shield containing-material layer and the top magnetic shield containing-material layer both comprise a magnetic shield that provides Faraday shielding for RF magnetic fileds, a magnetic shield material composed of μ-metal, a magnetic shield material composed of a superconductor material, or any multilayered stack thereof.
