Abstract: A conductive drive line configuration for propagating binary information in a cross-tie wall memory system is disclosed. The drive line includes serially-intercoupled portions, each of which defines a memory cell, that are overlaid and uniformly spaced along a cross-tie wall in a ferromagnetic layer. Each portion includes two separate segments, a transfer segment and a memory segment, that overlay keepers of high magnetic remanence. The keepers provide permanent localized fields, at their ends, that are normal to the plane of the layer while the current energized sections provide pulsed localized fields, normal to their edges, that, in the plane of the layer, are antiparallel to each other and normal to the cross-tie wall. The keepers'' localized fields are utilized to stabilize the position of an inverted Neel wall section (which inverted Neel wall section is bounded by a crosstie on one end and a Bloch-line on the other end) of the crosstie wall during transfer of an inverted Neel wall section from memory cell to memory cell serially along the cross-tie wall.
