Abstract:
1. A magnetic memory, comprising: a plurality of lead structures, disposed on a substrate, wherein the lead structures do not intersect each other; a plurality of first magnetic metal structures, disposed on the substrate, wherein each of the first magnetic metal structures is disposed between adjacent two of the lead structures; a second magnetic metal structure, disposed on the substrate, covering the lead structures and the first magnetic metal structures, and spanning over the lead structures, wherein a structure formed by the first magnetic metal structures and the second magnetic metal structure comprises 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, and the magnetic domain is suitable for storing a bit data; and an insulation layer, disposed between the lead structures and the first magnetic metal structures and between the lead structures and the second magnetic metal structure.
