Abstract
PURPOSE: To reduce the loss time of the processing by cancelling once the execution time storing the error data and then storing the correct data for continuation of the data process.
CONSTITUTION: The data necessary for process is read out of memory unit 1 and then stored into memory data register 2 through reading data bus (a) and memory data selector 3. When the bit error is detected to the data at error detection circuit 6, correction control signal (A) is applied to error correction circuit 7 and clock control circuit 8. With indication of signal (A), the correction of the error bit is given to the data of memory reading register 4. Thus, the correct data is sent to correction data bus 6. At the same time, the processing is retarded by one time for clock control circuit 8 received the error control signal in order to store again the correct reading data after correction into the memory data register.
