Patent ID: 7848136

Claim:
A magnetic memory which has memory cells, each of the memory cells comprising: a storage element comprising a magnetic recording layer whose magnetization direction changes according to an external magnetic field, a magnetization pinned layer whose magnetization direction is pinned, and a non-magnetic layer provided between the magnetic recording layer and the magnetization pinned layer; a writing wire which is provided on the magnetic recording layer on a side opposite to a side on which the non-magnetic layer is disposed, and in which writing current flows; and a yoke which is provided on the writing wire only on a side opposite to a side on which the magnetic recording layer is disposed, and which is provided along a first direction in which the writing wire extends, and the yoke comprising a planar shape different from a planar shape of the magnetic recording layer, a longitudinal axis of the magnetic recording layer being inclined to a second direction perpendicular to the first direction by an angle of more than 0° and less than 90°, the planar shape of the magnetic recording layer has a maximum width in the first direction positioned at a central portion of the magnetic recording layer in the second direction, and the planar shape of the magnetic recording layer includes a pair of opposed sides along the longitudinal axis of the magnetic recording layer, each entirety of the pair of the opposed sides being a curved line, a pair of side faces along the first direction of the storage element being positioned on the same plane as a pair of opposed side faces of each of the writing wire and the yoke, and the magnetic recording layer being electrically connected to the writing wire.
