Abstract
A magnetic memory device includes a substrate, a landing pad on the substrate, first and second magnetic tunnel junction patterns disposed on the interlayer insulating layer and spaced apart from the landing pad when viewed from a plan view, and an interconnection structure electrically connecting a top surface of the second magnetic tunnel junction pattern to the landing pad. A distance between the landing pad and the first magnetic tunnel junction pattern is greater than a distance between the first and second magnetic tunnel junction patterns, and a distance between the landing pad and the second magnetic tunnel junction pattern is greater than the distance between the first and second magnetic tunnel junction patterns, when viewed from a plan view.
