Abstract
PURPOSE: To increase the maintainability through the defective parts, by detecting the error in the stored data due to interface failure through the use of error check correction and producing circuit.
CONSTITUTION: The main memory control unit 2 has the error check, correction ECC check bit generating circuit 4, the check bit is produced at this production circuit at the storage operation to the main memory unit 1, check bit is added to the stored data and transferred to the margin circuit 8. Further, after setting it to the stored data register 6 via the circuit 8, the selection circuit 7 selects the ECC check correction to check the error in single or multiplex bit. When the error in multiplex bit due to failure in the interface is detected, the stored data in error is collected, faulty location is retrieved, and when single bit error is detected, the circuit 4 corrects the data, and it is stored 6 with the check code added. Thus, defective parts are sectioned to increase the maintainability.
