Abstract

PURPOSE: To prepare many switching storage elements for the fixed faults of storage elements in each device and to attain diagnosis prior to switching by adding a switching storage element to a memory card and connecting a diagnosis circuit.
CONSTITUTION: A control signal 15 is applied from a control part and information corresponding to a storage element 1-1 is impressed to a memory card on the basis of a fault bit specifying signal 12. Then, the control part sets up all address spaces applied to the element 1-1 to rewriting/rereading operation, reads out data while ascending addresses and applies the read data to an error correcting circuit to correct the information of a fault bit. In case of reading operation, storage information 1-1...1-N on a memory card is sent to the control part through respective selecting elements 7-1...7-N. Since rewriting operation is executed, the fault of the storage element 1-1 is written in an additional storage element 1-N+1.
