Abstract
A conductor access, magnetic bubble memory is organized in a major-minor mode by including transfer locations in the conducting layers which define the normal bubble propagation implementation. An attractive partitioning of each of the two conducting layers permits the minor loops and the major loop to be operated synchronously or independently resulting in short duty cycles which permit low power operation to be achieved.
