Abstract

PURPOSE:To attain rapid data retrieval by means of the small number circuits by providing the titled device with exclusive control circuits respectively executing the addition of a record, the change of the contents of the record, and retrieving the record. CONSTITUTION:An addition control circuit 15 determines a position in a rapid readable/writable storage device 11 by the contents of a counter circuit 12 and adds a record. A change control circuit 16 determines a position in the device 11 by the contents of a pointer circuit 13 and changes the contents of a record. A retrieval control circuit 17 changes the contents of a pointer circuit 13, reads out keys of records stored in the device 11 successively and compares the read key with the contents (the key of a record to be retrieved) of a temporary storage circuit 14. Said operation is repeated until a coincident key is detected or until a comparison for all records indicated by the counter circuit 12 is completed.
