Abstract:
1. A magnetic storage device, comprising: a magnetic storage element having a tunnel barrier layer, a lower ferromagnetic material layer and an upper ferromagnetic material layer, where the lower and upper ferromagnetic material layers sandwich the tunnel barrier layer; and a pair of interconnects which are in mutually twisted positions above and below the magnetic storage element, being insulated and separated from each other, wherein the interconnect positioned above the magnetic storage element of the pair of interconnects is coupled to the upper ferromagnetic material layer, and the interconnect positioned below the magnetic storage element of the pair of interconnects is insulated from the lower ferromagnetic material layer; wherein the lower ferromagnetic material layer is coupled to a selection transistor; and wherein at least one of the pair of interconnects includes a local curved portion, which is spaced from the magnetic storage element so as to surround the magnetic storage element.
