Abstract
A repair circuit includes a test data processing unit that outputs first and second fail detection signals using first and second test data of first and second memory banks, respectively, in response to a test mode signal, a repair address control unit that sets a priority of the first and second memory banks and selectively stores first and second addresses of the first and second memory banks based on the set priority in response to the first and second fail detection signals, and a fuse unit that performs repair programming based on the addresses selectively stored in the repair address control unit.
