Summary:PROBLEM TO BE SOLVED: To provide a control system with improved reliability by detecting even a failure of an address line before writing data into a wrong address. SOLUTION: A system control circuit 120 transfers data to a memory 140, and writes the data to the assigned address of the memory 140 or reads the data from the assigned address of the memory 140. An error detecting circuit 134 of a memory control device 130 detects the error of the address assigned to the memory 140. A control circuit 136 allows the data transfer to the memory 140 when the assigned address is correct. COPYRIGHT: (C)2007,JPO&INPIT
