What are the specific repair addresses provided by the repair control circuit?
The repair control circuit provides repair addresses based on the row address to target specific memory cells for repair.
How does the column control circuit determine which redundancy column selection lines to activate?
The column control circuit activates redundancy column selection lines based on the row-hammer flag signals or by comparing the column address with the repair addresses provided by the repair control circuit.
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.
