Methods of operating magnetic memory devices

A method of operating a magnetic memory device includes: (i) applying a first current to a free layer of a magnetic tunnel junction structure, which includes a magnetic translation unit (MTU) extending between a first magnetic pad and a second magnetic pad, and a tunnel barrier layer and a pinned layer stacked on the MTU, so that a multi-domain is established within the MTU, (ii) applying a magnetic field to the free layer so that the magnetization direction of the MTU switches to become anti-parallel to the magnetization directions of the first magnetic pad and the second magnetic pad, (iii) applying a second current to the free layer so that a portion of the multi-domain penetrates into the first magnetic pad, and (iv) applying another magnetic field to the free layer so that the magnetization direction of the first magnetic pad switches.
