A magnetic memory device includes a conductive line extended in a first direction and a magnetic track line provided on a top surface of the conductive line and extended in the first direction. The magnetic track line includes a domain injection portion and a line portion, which is extended from the domain injection portion in the first direction. The domain injection portion has a tapered shape in an opposite direction of the first direction. The conductive line has a linewidth in a second direction, and the first and second directions are parallel to the top surface of the conductive line and are perpendicular to each other. Below the domain injection portion, a first linewidth of the conductive line remains constant in the opposite direction of the first direction.

Abstract
A magnetic memory device includes a conductive line extended in a first direction and a magnetic track line provided on a top surface of the conductive line and extended in the first direction. The magnetic track line includes a domain injection portion and a line portion, which is extended from the domain injection portion in the first direction. The domain injection portion has a tapered shape in an opposite direction of the first direction. The conductive line has a linewidth in a second direction, and the first and second directions are parallel to the top surface of the conductive line and are perpendicular to each other. Below the domain injection portion, a first linewidth of the conductive line remains constant in the opposite direction of the first direction.
