Abstract
A conductor-access, magnetic bubble memory is realized with a single metallization level for propagation. The familiar undulating or serpentine conductor pattern used for moving bubbles is modified to allow a simple and easily realizable, low power drive arrangement where currents flow parallel to the bubble paths.
