Claim Text:
1. A magnetic memory comprising at least one element, the element comprising: a multilayer structure including a first magnetic layer in which a direction of magnetization is fixed, a second magnetic layer in which a direction of magnetization is changeable, and a nonmagnetic layer located between the first magnetic layer and the second magnetic layer, the multilayer structure having a first surface, a second surface opposed to the first surface, and a side surface different from the first surface and the second surface; a first electrode provided on the first surface of the multilayer structure and electrically connected to the first magnetic layer; a second electrode provided on the second surface of the multilayer structure and electrically connected to the second magnetic layer; an insulating film provided on the side surface of the multilayer structure; a control electrode provided on the side surface of the multilayer structure with the insulating film located therebetween; a voltage applying circuit that applies a voltage to the control electrode in a read operation; and a readout circuit that flows a read current between the first electrode and the second electrode to read information from the element.
