Abstract: A magnetic memory device includes a loop-type magnetic track having a first part and a second part that are arranged in a counterclockwise direction, a first conductive line on a top surface of the first part, and a second conductive line on a bottom surface of the second part. The magnetic track includes a lower magnetic layer, a spacer layer, and an upper magnetic layer that are sequentially stacked. Each of the first and second conductive lines includes heavy metal. Each of the first and second conductive lines is configured to generate spin-orbit torque caused by current that flows therein. The spin-orbit torque causes magnetic domains in the magnetic track to move in a clockwise direction or in the counterclockwise direction.
