    Abstract: The present disclosure relates to operation methods of a memory device including multiple rows each including multiple memory cells. One example method includes receiving an active command for a first row from a memory controller, reading a first count from a per-row hammer tracking (PRHT) region of the first row, updating the first count to generate a first updated count, comparing the first updated count with one of first and second thresholds to generate a comparison result, wherein when the first row is adjacent to the given row, the first updated count is compared with the first threshold and when the first row is not adjacent to the given row, the first updated count is compared with the second threshold, outputting a target row address based on the comparison result, and performing a row hammer mitigation operation on a row corresponding to the target row address.
