Patent ID: 7411263

Claim:
A magnetic memory device comprising: a magnetoresistive element including a fixed layer having a direction of magnetization thereof fixed, a recording layer having a direction of magnetization thereof varied, and a non-magnetic layer interposed between the fixed layer and the recording layer; and a first wiring layer extending in a first direction and configured to generate a magnetic field for recording data in the magnetoresistive element, wherein the recording layer includes: a base portion extending in a second direction rotated from the first direction by an angle falling within a range of more than 0° to not more than 20°, the base portion including a first side and a second side opposing each other and extending in the second direction, the base portion also including a third side and a fourth side opposing each other; and a first projection and a second projection outwardly projecting from the first side and the second side, respectively, in a third direction perpendicular to the second direction, the third side-and the fourth side being inclined with respect to the third direction in the same rotational direction as a rotational direction in which the second direction is rotated.
