ABSTRACT:
A low power, conductor-access, bubble memory is realized with a single level of metallization for providing the requisite propagation fields. Sets of apertures in the conducting layer define bubble paths, and permalloy elements aligned with the apertures overlie the conducting layer at end portions and contact the exposed bubble layer at midportions. Current flow is established transverse to the bubble paths.
