ABSTRACT:
A method of and an apparatus for reading out the information that is stored in the magnetizable layer of a cross-tie wall memory system is disclosed. The apparatus utilizes: a conductive pillar that is centered over and is conductively coupled to the Bloch-line position in the memory segment of the cross-tie wall in the magnetizable layer; a conductive ring that is oriented concentric to the pillar and that is conductively coupled to the magnetizable layer; and a readout device that is coupled across the pillar and ring for determining the resistance in the magnetizable layer between the pillar and ring as an indication of the existence or not of a Bloch-line in the memory segment.
