Abstract

PURPOSE: To prevent the trouble to exchange a P-ROM at each time of memory element exchange, by rewriting defect information corresponding to each magnetic bubble memory element onto a RAM in the apparatus main body and controlling the magnetic bubble-memory.
CONSTITUTION: Defect information of used magnetic bubble memory element 11 is inputted from input device 12 and is rewritten and stored in non-volatile RAM 14 through CPU 13. Control circuit 15 refers to contents of this non-volatile RAM 14 to control magnetic bubble memory 11. In case of magnetic bubble-memory element 11 exchange, defect information of a new magnetic bubble-memory element is inputted from input device 12, and contents of non-volatile RAM 14 are rewritten, so that the trouble to exchange a P-ROM can be omitted.
