Abstract
A magnetic bubble memory, in which the PI junction between a first propagation track defined by deposited patterns and a second propagation track defined by the boundary between an implanted zone and a non-implanted zone is defined by an overlap between such propagation tracks, wherein the overlap zone has a surface substantially equal to the surface of a magnetic bubble and forms a stable position for each of the two propagation paths.
Claims7
A hybrid magnetic bubble memory having a sequence of deposited patterns aligned along an easy magnetization axis of a magnetic material of the memory and forming a first propagation track for magnetic bubbles, and a sequence of non-implanted patterns aligned along the same axis and defining a second propagation track along a boundary between an implanted zone and a non-implanted zone, A junction extending between said first and second propagation tracks to enable a magnetic bubble to pass from the first track to the second track and being defined by an overlap zone between said propagation tracks, said overlap zone having a surface of the order of magnitude of the size of a magnetic bubble and forming for each of the propagation tracks a stable position for the magnetic bubble.
