Abstract
A magnetic memory, a driving method thereof, and a manufacturing method thereof are provided. The magnetic memory includes a plurality of lead structures, a plurality of first magnetic metal structures, a second magnetic metal structure, and an insulation layer. Each of the first magnetic metal structures is disposed between adjacent two of the lead structures, and the second magnetic metal structure spans over the lead structures. A structure composed of the first magnetic metal structures and the second magnetic metal structure includes a plurality of magnetic memory cells connected with each other. Each of the magnetic memory cells has a magnetic domain and a domain wall adjacent to the magnetic domain, wherein the magnetic domain is suitable for storing a bit data.
