PROBLEM TO BE SOLVED: To provide a data communication system capable of error correction without adding a complicated circuit. SOLUTION: This data communication system comprises a CPU 10, a write address selection circuit 11, an ECC generation circuit 12, a RAM 13, a read source selection circuit 14, an ECC correction circuit 15, and a serial communication circuit 16. Thus, an error correction code generation function and/or an error correction function out of error correction functions included in a memory is utilized for the transmission and/or reception of data to/from the outside. Accordingly, since the error correction code generation function and/or the error correction function used in the memory can be utilized as it is for the transmission and reception of data, an error correction can be made without adding a complicated circuit.
