Abstract

A magnetic memory of an embodiment includes: a first magnetic member including a first and second portions and extending in a first direction; a first and second wirings disposed to be apart from the first magnetic member and extending in a second direction intersecting the first direction, the first and the second wirings being separated from each other in a third direction intersecting the first and second directions, the first magnetic member being disposed to be apart from a region between the first wiring and the second wiring in the first direction; and a second magnetic member surrounding at least parts of the first and second wirings, the second magnetic member including a third portion located to be more distant from the first magnetic member, a fourth portion located to be closer to the first magnetic member, and a fifth portion located in the region.

Dependent claims

A magnetic memory comprising:

a first magnetic member including a first portion and a second portion and extending in a first direction from the first portion to the second portion;
a first wiring and a second wiring disposed to be apart from the first magnetic member and extending in a second direction that intersects the first direction, the first wiring and the second wiring being separated from each other in a third direction that intersects the first direction and the second direction, the first magnetic member being disposed to be apart from a region between the first wiring and the second wiring in the first direction;
and
a second magnetic member surrounding at least a part of the first wiring and at least a part of the second wiring, the second magnetic member including a third portion that is located to be more distant from the first magnetic member than the first wiring and the second wiring in the first direction, a fourth portion that is located to be closer to the first magnetic member than the first wiring and the second wiring in the first direction and electrically connected to the first portion of the first magnetic member, and a fifth portion that is located in the region between the first wiring and the second wiring and electrically connected to the third portion and the fourth portion.
