Abstract

Abstract A magnetic domain switching matrix arrangement is realized by a magnetically soft overlay geometry which controls the movement of single wall domains in a slice of magnetic material in response to a reorienting magnetic field. The overlay geometry defines a switching matrix for domains propagated along a horizontal path, which domains are selectively transferred to an intersecting vertical path under control of a domain positioned in proximity to the selected intersection between the respective paths. A separate control grid is utilized to position the control domain at the desired intersection point. Also realized are arrangements for controllably delaying and for selectively routing the control domains in accordance with information domains propagated in separate control channels in a flow chart arrangement.
