Original Abstract Submitted
A magnetic memory device may include conductive lines provided in cell region and peripheral region, a first insulating layer provided in the cell region and the peripheral region, and surrounding the conductive lines, a second insulating layer provided on the first insulating layer in the cell region and the peripheral region, and on top surfaces of the conductive lines, and data storage patterns provided on the second insulating layer in the cell region and electrically connected to corresponding conductive lines of the conductive lines. The second insulating layer in the peripheral region may include first portions on the top surfaces of the conductive lines, and second portions disposed between the first portions. Top surfaces of the first portions may be disposed at a level higher than top surfaces of the second portions.
