    Abstract: A single wall domain propagation arrangement herein includes magnetically soft overlay patterns which generate magnetic poles in response to reorienting inplane fields to move domains in propagation channels defined thereby. The arrangement is organized for high packing density and fast access by providing parallel recirculating bit channels to move consecutive binary word representations to a common recirculating channel. The common channel moves the word to a common read-write area. Information moves synchronously in the common channel, as well as in the parallel channels, permitting the return of information to the parallel channels with little logic circuitry.

    Abstract: Interactions between single wall domains permit logic operations to be realized in magnetic sheets in which such domains are moved. Magnetically soft overlay patterns not only define propagation channels for such domains in response to magnetic fields reorienting in the plane of the sheet but also define channel intersections where logic functions are carried out. Domains are idled or, alternatively, in direction at those intersections depending on the positions of preceding domains. A variety of counter circuits are described.

    Abstract: A read-only domain propagation memory is realized by appliqueing magnetic traps for single wall domains along a propagation channel for such domains. The traps can be defined by a magnetically soft or by a permanent magnet overlay arrangement which extracts a preset pattern of domains from the propagation channel responsive to a control signal. The overlays are removable to permit a change in the domain pattern.

    Abstract: A single wall domain propagation arrangement wherein magnetically soft overlays define propagation channels in a sheet of magnetic material in response to a reorienting in-plane field is adapted herein for providing a ''''coincident-domain'''' memory. The overlay at each bit location of the memory is structured to serve the function of a latching switch. A domain pattern advanced along one of coordinate domain propagation accessing channels is rerouted to the coordinate channel when the associated switch is closed.
