According to one embodiment, a magnetic memory device includes a first memory unit including a first memory array and a first drive unit, a second memory unit including a second memory array and a second drive unit, and a controller. The first memory array includes a first magnetic shift register unit. The second memory array includes a second magnetic shift register unit. The controller subdivides input data into a plurality of one-dimensional bit input arrays. The one-dimensional bit input arrays include a first array and a second array. The controller stores the first array in the first magnetic shift register unit on a last in, first out basis, and stores the second array in the second magnetic shift register unit on a last in, first out basis.
