Abstract
An information storage device includes a storage node, a write unit configured to write information to a first magnetic domain region of the storage node, and a read unit configured to read information from a second magnetic domain region of the storage node. The information storage device further includes a temporary storage unit configured to temporarily store information read by the read unit, and a write control unit electrically connected to the temporary storage unit and configured to control current supplied to the write unit. The information read from the second magnetic domain region is stored in the temporary storage unit and written to the first magnetic domain region.
