Original Abstract Submitted
A memory device includes: a memory cell region including normal cells coupled to normal column selection lines, and row-hammer cells and redundancy cells respectively coupled to redundancy column selection lines; a repair control circuit configured to provide repair addresses and row-hammer flag signals, corresponding to repair information, according to a row address; and a column control circuit configured to activate at least one of the redundancy column selection lines according to the row-hammer flag signals or a comparison result of a column address and the repair addresses.
