Abstract
A memory device having an error notification function includes an error correction code (ECC) engine detecting and correcting an error bit by performing an ECC operation on data of the plurality of memory cells, and an error notifying circuit configured to output an error signal according to the ECC operation. The ECC engine outputs error information corresponding to the error bit corresponding to a particular address corrected by the ECC operation. The error notifying circuit may output the error signal when the particular address is not the same as any one of existing one or more failed addresses.
