Abstract

PURPOSE: To obtain the error detection and correction unit to prevent the correction in error, by comparing the output with duplicating the part judged as correctable error for the partial failure of the code generation circit and the code inspection circuit with the code detection circuit.
CONSTITUTION: The data Di0 to Di7 given externally are inputted to the even number parity generation circuit PG and the element data Pi0 is duplicatedly formed. The circuit PG is provided for the system judged as one bit error in case of failure, humming code generation circuit and the inspection circuit respectively. The output of each circuit PG is inputted to the OR circuit and it is fed to FF via the AND circuit outputting the output at the time point causing the timing pulse TR. The output of FF is inhibit signal of one bit error correction operation. Thus, if the forming circuit system of the original data Pi0 of the humming code generation circuit and inspection circuit is in failure and errored output is produced, the output of the circuit PG is produced, causing the FF to be reset and inhibiting the one bit error correction operation.
