Abstract
Disclosed is a cross-tie wall memory system for the generating, propagating and detecting of binary data represented by the presence or absence of cross-tie, Bloch-line pairs along a cross-tie wall in a thin magnetic layer. The system includes a three-level structure comprised of the following superposed layers: a straight-edged current conductive stripline; a serrated-edged thin magnetic layer data track, and a wide-narrow-edged current conductive stripline terminated on one end by a cross-tie, Bloch-line pair generator. A cross-tie detector is positioned intermediate the ends of the data track and is sandwiched between the data track and the wide-narrow-edged current conductive stripline. An N-bit data word is stored in the data track between the generator and the detector, is shifted through the detector for readout of the stored data word and is then restored into its original stored position by being shifted in a reverse manner along the data track and back through the detector.
