Abstract:
A refresh control circuit of a semiconductor apparatus includes a repair address processing unit configured to compare refresh addresses and repair information, activate a redundant enable signal, and convert the semiconductor apparatus into the same operation state as an initialization state of the repair information in response to activation of a repair initialization signal; a refresh counter configured to count the refresh addresses extended to a signal bit in response to activation of a redundant count enable signal; and a refresh control unit configured to activate the repair initialization signal and the redundant count enable signal when an additional refresh mode is set in response to a refresh command.
