Abstract
A magnetic memory device includes a lower contact plug on a substrate and a data storage structure on the lower contact plug. The data storage structure includes a bottom electrode, a magnetic tunnel junction pattern, and a top electrode that are sequentially stacked on the lower contact plug. The lower contact plug and the data storage structure have a first thickness and a second thickness, respectively, in a first direction perpendicular to a top surface of the substrate. The first thickness of the lower contact plug is about 2.0 to 3.6 times the second thickness of the data storage structure.
