Abstract
A Row Hammer Refresh Address (RHA) calculation method, calculation circuit, and semiconductor memory device that are capable of performing RHA calculation at high speed on a small circuit scale are provided. The control unit of the RHA calculation circuit preferentially calculates the address obtained using a lighter operation (merely by inverting the least significant bit) as the adjacent RHA between the adjacent RHAs on both sides based on the refreshed seed address when the seed address is refreshed. Alternatively, it preferentially calculates the address obtained using a lighter operation (merely by inverting the least significant bit) as the further adjacent RHA between the further adjacent RHAs on both sides based on the refreshed seed address when the seed address is refreshed.
