摘要：
A magnetic domain wall memory apparatus with write/read capability includes a plurality of coplanar shift register structures each comprising an elongated track formed from a ferromagnetic material having a plurality of magnetic domains therein, the shift register structures further having a plurality of discontinuities therein to facilitate domain wall location; a magnetic read element associated with each of the shift register structures; and a magnetic write element associated with each of the shift register structures, the magnetic write element further comprising a single write wire having a longitudinal axis substantially orthogonal to a longitudinal axis of each of the coplanar shift register structures.
