Abstract: An MRAM device includes a substrate; plural conductive lines, including a bit line and a word line; and a MTJ stack including a pair of magnetic yoke structures, wherein each of said yoke structures surrounds a conductive line. A method of fabricating a magnetic yoke in an MRAM structure includes preparing a substrate; forming a first conductive line on the substrate; fabricating a MTJ stack, including fabricating a first magnetic yoke structure about the first conductive line; forming a second conductive line on the MTJ stack; fabricating a second magnetic yoke about the second conductive line; depositing a layer of oxide on the structure; and metallizing the structure.
