PURPOSE:To realize the connection for an error of the readout data, by making use of the idle time in the readout access of a memory and accordingly avoiding a delay of the readout time of the data. CONSTITUTION:An address designation is given by a control circuit 12 when the normal readout is carried out to a memory device 11, and the readout data is supplied to the circuit 12 via selector 14. At the same time, an error correction circuit 13 designates an address to the memory 11 after confirming by a status signal ST that the circuit is not reading out the data to the memory 11, and introduces the readout data to perform a CRC checking. Then the address is stored in a register 15 when an error is detected, and at the same time the contents of the address where the error is caused is corrected. Thus a correct data is stored in a register 16. After this, the selector 14 supplies the data of the register 16 to the circuit 12. |
