Abstract
A magnetic memory device includes a conductive line extending in a first direction, a bottom electrode provided on a portion of a bottom surface of the conductive line, a free layer and a pinned layer stacked on the conductive line, a spacer layer between the free layer and the pinned layer, and a top electrode provided on a portion of a top surface of the pinned layer. The conductive line, the free layer, the pinned layer and the spacer layer have side surfaces perpendicular to the first direction, and the side surfaces are aligned with each other.
