摘要： A magnetic memory device includes a recording layer, a reference layer, a first input portion and a second input portion. The recording layer has perpendicular magnetization direction and a plurality of magnetic domains, and the reference layer corresponds to a portion of the recording layer and has a pinned magnetization direction. The recording layer has a data storage cell wherein a plurality of data bit regions each including a magnetic domain are formed. The magnetic domain corresponds to an effective size of the reference layer. The first input portion inputs at least one of a writing signal and a reading signal. The second input portion is electrically connected to the recording layer and inputs a magnetic domain motion signal in order to move data stored in a data bit region of the recording layer to an adjoining data bit region.
