A magnetic memory included a conductive line that extends in a first direction along a substrate. A first columnar body is in a memory cell array region of the substrate and extends in a second direction from the substrate. A first end of the first columnar body contacts the conductive line. The first columnar body is comprised of a first magnetic material and has magnetic domains adjacent to one another along a length of the first columnar body in the second direction. A second columnar body is in a peripheral region of the substrate and extending in the second direction from the substrate. A first end of the second columnar body contacts the conductive line, and a second end is connected to a control circuit. The second columnar body also is comprised of the first magnetic material.
