A semiconductor memory device has a memory circuit, a code tagging section, an error processing section, and a changeover circuit. The memory circuit writes and reads data into and from a memory area designated by an address signal. The code tagging section includes a write data register and an error correction code generation circuit for tagging an error checking code to input data, and sending it to the memory circuit as write data. The error processing section includes an error detection circuit and an error correction circuit for checking presence of an error after receiving read data from the memory circuit and correcting it when detected. The changeover circuit sends data from the code tagging section to the error processing section, and sends data from the code tagging section to the error processing section only when the address signal does not designate a memory area in the memory circuit.
