Abstract
A repair control device for memory cells divided into a plurality of banks may include a failed address storage circuit configured to sort and store a plurality of failed addresses each containing a failed bank address and a failed row address, according to the failed row address, and store the failed row address by matching the failed row address with total failed bank information representing one or more failed banks indicated by the failed row address. The repair control device also includes an address comparison circuit configured to compare an input address to a pair comprised of the failed row address and the total failed bank information, stored in the failed address storage circuit, and generate a hit signal based on the comparison result. The repair control device further includes an address generation circuit configured to generate an access target address based on the hit signal.
