ABSTRACT:
A magnetic bubble memory device according to this invention is characterized in that an electrical conductor which supplies a current pulse for driving gates having a replicating function is divided into a plurality of parts. The divided parts are connected to current pulse generator means in a mutually parallel relationship. As the current pulse generator means, accordingly, a pulse driver circuit whose output is a low voltage can be used. As a result, the cost of the pulse driver circuit is low.
