    摘要: Example embodiments may provide a magnetic device using magnetic domain dragging and a method of operating the same. An example embodiment magnetic device may include a data storage cell with a free layer having a switchable magnetization direction and a plurality of adjoining magnetic domains, a reference layer formed to correspond to a portion of the free layer and having a pinned magnetization direction, wherein a plurality of data bit regions may be formed in an array in the free layer, each of the data bit regions being formed with an effective size unit of the reference layer, so that the data storage cell may store a plurality of bits of data in an array, and a first input portion electrically connected to at least one of the data bit regions of the free layer and the reference layer to apply at least one of a writing signal and a reading signal; and a second input portion electrically connected to the free layer to drag data stored in data bit regions of the free layer toward an adjacent data bit region, and applying a dragging signal for magnetic domain dragging.
