Patent ID: 8139402

Claim:
A magnetic memory device comprising: a strap wiring; a contact via electrically coupling together the strap wiring and portions positioned under the strap wiring; and a magnetic recording element arranged at a distance from the formation position of the contact via as viewed on a plane and formed over the strap wiring, wherein the magnetic recording element includes: a fixed layer whose direction of magnetization is fixed; and a recording layer which is formed over the fixed layer and whose direction of magnetization is changed by an external magnetic field, wherein the planar shape of the recording layer is asymmetric with respect to the direction of the easy magnetization axis of the recording layer and is symmetric with respect to the axis of symmetry perpendicular to the easy magnetization axis, and wherein the contoured portion of the recording layer on the side closer to the center of area of the recording layer is opposed to the contact via side.
