A bubble memory organization with a plurality of storage loops in-plane folds allows the selective spacing of transfer and other functional elements from each other eliminating crowded conditions at loop ends. This permits the selective placement of the functional elements for the maximization of operating margins. This can also lead to reduced current requirements because passive replicate elements may be used, to reduced transfer line impedances, to reduced number of conductor lines and to a reduced number of transfer points per memory array. For the designs where passive replication is chosen, reliability is improved due to the reduction in current density to levels further below the conductor electromigration thresholds.
