PURPOSE:To shorten a restarting time when there is a fault by holding the address of a data read out from a memory when the fault occurs at the data, and writing the prescribed data only into that address after a fault processing is ended. CONSTITUTION:When an intermittent fault of a software error, etc., is generated at a memory 4, and the data of the address in the memory 4 is inverted by one bit, a parity error is generated at a read data. A fault detection circuit 5 detects this parity error, and when a fault address register 3 fetches the address of fault occurrence, it indicates the fault address register 3 to hold the address, and executes occurrence report to a fault processing part in an information processor. When the fault processing part receives the fault occurrence report from the fault detection circuit 5, it resets a flip-flop and registers, etc., in the processor except for the fault address register, and indicates the restart. |
