PURPOSE:To prevent an arbitrary stop of a magnetic bubble device during an access by discontinuing the actuation of the bubble device after the end of an access in case the bubble device has an abnormality during said access. CONSTITUTION:The OR processing is carried out between a high-level abnormality detecting signal 16 produced when a magnetic bubble memory device 5 has an abnormality during an access and a high-level magnetic bubble transfer signal given from a device control circuit 2. Then the production is controlled for a low-level magnetic bubble stop signal 18, and this signal 18 is supplied to the circuit 2 as a power-down signal. Therefore the device 5 is stopped after the access is through with the circuit 2. This prevents an arbitrary stop of the device 5 during an access. Thus it is possible to finish satisfactorily the actuation of the device 5 in response to its access in case an abnormality occurs owing to a temperature change which takes a long period of time to give its effect. |
