An electronic device is provided. The electronic device according to an embodiment of the present invention includes a semiconductor memory. The semiconductor memory includes: an inter layer dielectric film which is formed on a substrate, and has a hole; a conductive pattern having an upper plane located at the same level as an upper plane of the inter layer dielectric film actually by being buried in the hole; and a laminated structure which is connected to the conductive pattern on the conductive pattern, and includes a free layer having a changeable magnetization direction, a pinned layer having a fixed magnetization direction and a tunnel barrier layer interposed therebetween. The upper part of the conductive pattern may include an amorphous area. The objective of the present invention is to provide the electronic device which can secure the characteristics of a variable resistor, and has a low process level of difficulty. 전자 장치가 제공된다. 본 발명의 일 실시예에 따른 전자 장치는, 반도체 메모리를 포함하는 전자 장치로서, 상기 반도체 메모리는, 기판 상에 형성되고, 홀을 갖는 층간 절연막; 상기 홀에 매립되어 상기 층간 절연막의 상면과 실질적으로 동일한 레벨에 위치하는 상면을 갖는 도전 패턴; 및 상기 도전 패턴 상에서 상기 도전 패턴과 접속하고, 변경 가능한 자화 방향을 갖는 자유층, 고정된 자화 방향을 갖는 피고정층 및 이들 사이에 개재된 터널 베리어층을 포함하는 적층 구조물을 포함하고, 상기 도전 패턴의 상부는, 비정질 영역을 포함할 수 있다.
