PURPOSE:To improve the accessing efficiency to a memory by transmitting immediately the data read out of the memory as long as it is normal and then transmitting the data after correcting it when it is not normal. CONSTITUTION:An access control part 5 of a memory part 3 reads the data D out of a memory 7 through a reading part 8. When a detection part 9 detects an error of the data D, a contrl signal C is produced to start an error correction circuit 10. The circuit 10 corrects the errror of the data D and the produces a control signal C2. A gate part 11 is opend to transfer the control signal to a processor 1 via a common bus 4. When no error is detected by the part 9, the part 9 produces immediately a control signal C3 to open the gate 11 for transfer of data. The read-out transferred immediately as long as it is normal. In such a way, the access efficiency toa memory is improved. |
