Abstract:
In one implementation, an electronic device is provided to include a semiconductor memory, wherein the semiconductor memory may include: a variable resistance element including a Magnetic Tunnel Junction (MTJ) structure including a free layer having a changeable magnetization direction free layer, a pinned layer having a fixed magnetization direction and a tunnel barrier layer interposed between the free layer and the pinned layer, and the electronic device may further include, in a first direction in which the free layer, the tunnel barrier layer and the pinned layer are arranged, a first permanent magnet having a first surface facing a first surface of the variable resistance element and spaced from the variable resistance element, wherein a magnetic field generated by the first permanent magnet may have a direction which offsets or reduces an influence of a stray field generated by the pinned layer.
