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 17):
An apparatus, comprising:\n a memory array including a regular array and a redundant array; a refresh control circuit coupled to the memory array and configured to refresh memory cells of the regular array and the redundant array, wherein the refresh control circuit is configured to produce a plurality of refresh addresses responsive to a first refresh command and to detect whether the plurality of refresh addresses include defective addresses and non-defective addresses, and the refresh control circuit further configured to refresh the non-defective addresses without refreshing the defective addresses responsive to a second refresh command, wherein the refresh control circuit comprises: a refresh address counter configured to provide a portion of a refresh address; and a counter circuit configured to provide a plurality of counts that are each combined with the portion of the refresh address to produce the plurality of refresh addresses.
