A magnetic memory device may include a digit line on a substrate, a first insulating layer on the digit line, and a magnetic tunnel junction memory cell on the first insulating layer so that the first insulating layer is between the digit line and the magnetic tunnel junction memory cell. A second insulating layer may be provided on the magnetic tunnel junction memory cell, wherein the second insulating layer has a hole therein exposing portions of the magnetic tunnel junction memory cell. A bit line may be provided on the second insulating layer and on portions of the magnetic tunnel junction memory cell exposed by the hole in the second insulating layer, and ferromagnetic spacers may be provided on sidewalls of at least one of the digit line and/or the bit line. Related methods are also discussed.
