Abstract
Provided is an electronic device including a semiconductor memory. The semiconductor memory may include: an under layer including first and second metal layers and a barrier layer having a dual phase structure of different crystal structures and interposed between the first and second metal layers; a first magnetic layer positioned over the under layer and having a variable magnetization direction; a tunnel barrier layer positioned over the first magnetic layer; and a second magnetic layer positioned over the tunnel barrier layer and having a pinned magnetization direction, and the under layer may further include a barrier layer having a dual phase structure between the first and second metal layers.
