Abstract

A storage unit includes a U-shaped magnetic track, a first drive circuit, a second drive circuit, a first drive port, and a second drive port. The U-shaped magnetic track includes a first port, a second port, a first storage area, and a second storage area. By controlling input voltages of the first port, the second port, the first drive port, and the second drive port and driving the first drive circuit, a current pulse is generated in the first storage area, and a magnetic domain wall in the first storage area is driven to move. By controlling the input voltages of the first port, the second port, the first drive port, and the second drive port and driving the second drive circuit, a current pulse is generated in the second storage area, and a magnetic domain in the second storage area is driven to move.
