Abstract:
A magnetoresistive device of an embodiment includes: first and second devices each including, a first magnetic layer having a changeable magnetization perpendicular to a film plane, a second magnetic layer having a fixed and perpendicular magnetization, and a nonmagnetic layer interposed between the first and second magnetic layers, the first and second devices being disposed in parallel on a first face of an interconnect layer; and a TMR device including a third magnetic layer having perpendicular magnetic anisotropy and having a changeable magnetization, a fourth magnetic layer having a fixed magnetization parallel to a film plane, and a tunnel barrier layer interposed between the third and fourth magnetic layers, the TMR device being disposed on a second face of the interconnect layer, and the third magnetic layer being magnetostatically coupled to the first magnetic layers of the first and second devices.
