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.
