Abstract
A semiconductor device includes a flag generation circuit configured to receive region fuse data and used fuse data which are generated from a fuse set selected based on a fuse set selection signal among from fuse sets and generate a bank resource flag to control a repair operation for a bank on which a repair operation has not been performed, based on the region fuse data and the used fuse data. The semiconductor device also includes a repair control circuit configured to control the repair operation for banks sharing the fuse sets based on the bank resource flag.
