Classification: CPC G  H | IPC G  H

Claim 11:
12. A semiconductor device comprising:
an error correction circuit configured to detect an error included in internal data, to generate a failure detection signal during a read operation, and to correct the error included in the internal data during a refresh operation;
a core circuit configured to store an address signal for activating a word line in which the internal data including the error is stored as a failure address signal when the failure detection signal is input to the core circuit and store the error-corrected internal data in the core circuit through a word line activated by the failure address during the refresh operation; and
a repair control circuit configured to generate a repair signal for replacing the word line in which the internal data is stored through with another word line when the failure address signal is generated with the same logic level combination.
