Apparatuses and methods per-row count based refresh target identification. A memory device stores count values associated with the word lines. An aggressor detector circuit stores a maximum of the count values and a row address associated with the maximum count value. Responsive to a targeted refresh signal, the stored count value is compared to a threshold. If the count value has crossed the threshold, then a targeted refresh operation may be performed on one or more refresh addresses based on the stored address, and the count value may be reset.
