Abstract
A magnetic memory device may include tunnel junction unit cells, each including a pinned magnetic layer, an insulating layer, and a free magnetic layer which are sequentially stacked, a conductive line structure configured to supply an in-plane current to the unit cells and to include an antiferromagnetic layer, which is provided adjacent to the free magnetic layer, and a ferromagnetic layer, which is provided adjacent to the antiferromagnetic layer and has an in-plane magnetic anisotropy, and a voltage applying unit configured to independently apply a selection voltage to each of the tunnel junction unit cells. Each of the tunnel junction unit cells may have a magnetization direction that is selectively changed by the in-plane current and the selection voltage.
