摘要： A method of and an apparatus for counting is disclosed. The counter includes a generator of cross-tie, Bloch-line pairs and a shift register of N stages or memory cells along which the cross-tie, Bloch-line pairs are propagated or replicated into a detector. The method includes coupling a series of bipolar push-nucleate replicate signals, each one of which produces a cross-tie, Bloch-line pair in the adjacent downstream memory cell along the shift register. When the shift register is filled, a cross-tie will appear in the detector. This provides an output signal indicating that the N memory cells have been filled by the N replicate signals.

摘要： An improved magnetic memory system in which binary data are stored as cross-tie, Bloch-line pairs, which are serially propagated downstream along a cross-tie wall in a magnetizable layer by appropriate drive fields. The magnetizable layer is configured into a data track whose two opposing edges are formed into patterns of asymmetrically shaped edges which form successive narrow portions with wide portions therebetween, and which are formed about the geometric centerline of the data track. The improvement comprises forming a plurality of energy wells along the geometric centerline of the data track and, transverse to the geometric centerline of the data track in the areas of the narrow portions where the cross-ties are stored but not in the areas of the geometric centerline.

摘要： 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 data track. The system includes a three-level shift register structure comprised of the following layers: first and second substantially similar, serrated-edged current conductive striplines and a serrated-edged thin magnetic layer data track. The shift register is terminated on one end by a cross-tie, Bloch-line pair generator and on the other end by a cross-tie detector. A data word is stored in the data track between the generator and the detector and is shifted through the detector for readout of the stored data word. The first and second serrated-edged striplines are formed of alternate wide-narrow portions with the wide portion of one stripline oriented above/below the narrow portion of the other stripline. Current signals alternatively coupled to the first and second striplines generate drive fields of differing intensities in the plane of the inductively coupled data track for propagating the cross-tie, Bloch-line pairs therealong.

摘要： A method of and an apparatus for reading out the information that is stored in a magnetizable layer that is formed of a thin film in which data are stored as inverted Neel wall sections about associated Bloch-lines along a cross-tie wall. The apparatus utilizes a magnetizable layer which is configured into a strip whose two opposing edges are, along its longitudinal axis, formed into mirror-imaged, spaced-apart, repetitive, asymmetrically-shaped patterns which repetitive patterns are formed of successive narrow portions that form wide portions therebetween. The repetitive patterns, when suitable magnetic fields are coupled thereto, form a cross-tie wall along the longitudinal axis of the strip while structuring the cross-ties along the cross-tie wall at the narrow portions and the Bloch-lines along the cross-tie walls and between the adjacent narrow portions. One of the repetitive patterns is configured into a sharp film whose longitudinal axis is transverse the strip's longitudinal axis and whose transverse axis is along the strip's longitudinal axis. The sharp film, in the area extending beyond the strip's two opposing edges, comprises an open flux path film that possesses the characteristic of shape anisotropy providing a magnetic easy axis that is generally oriented along the sharp film's longitudinal axis and along which the sharp film's remanent magnetization resides wherein for all points on the sharp film's edge the angle .beta.' between the sharp film's edge and the sharp film's longitudinal axis is equal to or greater than 0.degree. and less than 45.degree.. Also disclosed is a detector that is associated with the sharp film for reading out the orientation of the sharp film's remanent magnetization along the sharp film's easy axis.

摘要： The memory system incorporates a memory element storing binary digital data in the presence, vel non, of a Y-domain cross-tie. The memory element has a planar contour that is substantially symmetrical about a longitudinal axis and that has edge portions that are nowhere perpendicular or parallel to the longitudinal axis. A stabilizing magnetic field applied perpendicular to the longitudinal axis and in the plane of the memory element forms a first Neel wall along the longitudinal axis and causes the magnetization in the memory element to be formed into first and second domains on opposite sides of the Neel wall. When a writing magnetic field oriented in the plane of the memory element and perpendicular to the longitudinal axis but opposite to the stabilizing magnetic field orientation is coupled to the memory element, there is formed in the memory element a third domain separated from the first and second domains by second and third Neel walls having a join with one end of the first Neel wall. The first, second and third Neel walls form a "Y". Because of the nature of this third domain having its magnetization oriented in a direction parallel to the readout current caused to pass through the memory element, it produces a significantly greater difference in the readout signal between the readout of a stored 1 and a stored 0 than that achieved with the prior art cross-tie wall memory element.

摘要： The method of and a configuration for reading out the information that is stored in a cross-tie wall memory system is disclosed. The apparatus utilizes: a continuously, relatively long, sense line that is aligned along and straddles the cross-tie wall; a first polarity hard axis drive field H.sub.Tt that passes, if in existence, a stored-1-representing-Bloch-line from a memory segment along the cross-tie wall into, along and past the continuous sense line; a second polarity hard axis drive field H.sub.Tn that nucleates many Bloch-lines at once along the cross-tie wall in the area of the sense line for causing the nucleating Bloch-lines to induce in the sense line an output signal that is indicative of the change in polarity of the Neel wall vectors within the cross-tie wall in the area of the sense line and, accordingly, whether or not a stored-1-representing-Bloch-line had been stored previously in the memory segment.

摘要： A method of and a configuration for reading out the information that is stored in a cross-tie wall memory system is disclosed. The apparatus utilizes: a cross-tie, Bloch-line pair transfer system for bit-serially moving a bit-defining-Bloch-line along the cross-tie wall into a memory segment; a noise-cancelling figure-8 sense line that straddles the cross-tie wall; a hard axis drive field H.sub.T that passes, if in existence, a bit-defining-Bloch-line out of the memory segment into one of the loops of the sense line and thus inducing in the sense line loop an output signal that is indicative of the passing, or not, of the Bloch-line into the sense line loop.

摘要： An improved magnetic memory system in which binary data are stored as cross-tie, Bloch-line pairs, which are serially propagated downstream along a cross-tie wall and a magnetizable layer by appropriate drive fields. The magnetizable layer is configured into a data track whose two mirror-image, opposing edges are formed into patterns of asymmetrically shaped edges which form successive narrow portions, or necks, with wide portions therebetween, and which shaped edges are formed about the geometric central line of the data track. The cross-ties are structured in the data track by opposite-edge necks at which the ends of the cross-tie are magnetically stable. The improvement comprises:forming a serpentine energy well along and about the geometric centerline of the data track, which energy well has the same period as the shaped edges;displacing the necks of the opposing edges one half the distance between adjacent necks along each edge; and,propagating the cross-tie, Bloch-line pairs along the data track by rocking alternate ends of the cross-tie from its associated neck to the next adjacent downstream neck.
