Abstract:
Apparatuses and methods for refreshing memory of a semiconductor device are described. An example method includes producing, responsive to a first refresh command, a plurality of first refresh addresses and detecting, responsive to the plurality of first refresh addresses, that the plurality of first refresh addresses include, a first defective address and a first non-defective address. The example method further includes refreshing, responsive to a second refresh command following the first refresh command, the non-defective first address without refreshing the first defective address.

Claim (Index 12):
The apparatus of  claim 11  wherein the row address control circuit comprises:\n a first latch configured to latch the first refresh address responsive to the first refresh command and to latch the second refresh address responsive to the second refresh command; \n a redundancy circuit configured to receive the latched first refresh address and prepare for the first refresh operation of the first memory locations and provide first redundancy information for the first refresh address to control the refresh operation of the first memory locations, and further configured to thereafter receive the latched second refresh address and prepare for the second refresh operation the second memory locations and provide redundancy information for the second refresh address to control the refresh operation of the second memory locations; \n a second latch circuit configured to latch the latched first refresh address from the first latch responsive to the second refresh command and to provide the first latched refresh address; and \n an address predecoder circuit configured to receive the redundancy information and the first latched refresh address and perform or skip refresh operations for one or more of the first memory locations based on the redundancy information.
