ABSTRACT:
A magnetic bubble memory device having a bubble generator which generates a magnetic bubble by conducting a pulse current on its hairpin-shaped conductor loop and a major propagation circuit for propagating the magnetic bubble to a transfer-in gate circuit which transfers the magnetic bubble to a memory storage region, wherein the device further comprises a gate means provided between the bubble generator and the major propagation circuit for transferring a magnetic bubble carrying information "1" onto the major propagation circuit at a first predetermined timing and preventing a spurious bubble to be transferred to the major propagation circuit at a second predetermined timing.
