Abstract
A conductor-access, magnetic bubble memory organized in the major-minor mode has minor loops separated into minor loop segments. The segments can be powered for moving bubbles selectively only within the corresponding segments of the minor loops. A transfer operation moves bubbles between minor loop segments permitting bubble movement to the major loop. The ability to move bubbles only in a selected set of corresponding segments of the loops at a time permits operation with highly attractive power requirements.
