The MRAM devices may include a magnetic tunnel junction (MTJ) including a free layer and a pinned layer sequentially stacked in a vertical direction and a conductive layer adjacent to the free layer of the MTJ. The conductive layer may include a horizontal portion and first and second protruding portions that protrude away from the horizontal portion and are spaced apart from each other in a horizontal direction that is perpendicular to the vertical direction. A side of the free layer and a side of the horizontal portion may form a straight side.
