MAGNETIC DOMAIN MULTIPLE INPUT AND CIRCUIT

摘要

A single wall domain, multiple-input, logical AND circuit is defined by an arrangement of magnetically soft overlay elements adjacent a sheet of material in which the domains can be moved. A plurality of propagation channels defined by the overlay elements include an orthogonal channel which comprises positions where domains are merely recirculated. When interrogated, the orthogonal channel provides an output only when all the idler positions are occupied.
