摘要： A serial magnetic mass storage device and associated data storage method of the kind in which data is encoded in single magnetic domains in nanowires. In the invention, the nanowires (10) are provided with a large number of notches (12) along their length to form domain wall pinning sites. Moreover, the notches are addressed in groups (A, B, C) by heating electrodes. By alternately heating the notches hosting head-to-head and tail-to-tail domain walls (16, 18) in synchrony with alignment and anti-alignment of an operating field (H) along the nanowire the magnetic domains (14) are moved along the nanowire by alternate movement of the head-to-head and tail-to-tail domain walls in caterpillar or worm-like motion in which the domains are incrementally lengthened and shortened by one inter-notch distance as they move along the nanowires under the joint coordinated action of the heating and alternating operating field. From an interconnect and fabrication standpoint, the scheme can be scaled almost without restriction out of the plane of the substrate to provide hundreds or thousands of stacked layers of nanowires, thus allowing very dense three- dimensional networks of stored information to be realised.

摘要： A serial magnetic mass storage device and associated data storage method is provided based on magnetic nanowires that support single magnetic domains separated by domain walls. Each data-storing nanowire has a plurality of crossing nanowires along its length, forming cross junctions that constitute domain wall pinning sites. Data is fed through each data-storing nanowire by moving the magnetic domains under the action of a field that alternates between alignment and anti-alignment with the crossing nanowires. The data is encoded in the chirality of the domain walls, with up and down chirality transverse domain walls being used to encode 0's and 1's. Data is clocked into each nanowire with suitable nucleation generators capable of nucleating domains with domain walls of pre-defined chirality. Data is clocked out of each nanowire with suitable magnetic field sensors that sense the chirality.
