Claim 8:
9. The circuit for refreshing a row hammer of claim 8, wherein the refresh execution signal comprises an initial refresh execution signal and a refresh pulse signal, correspondingly, the detection circuit comprises a first clock circuit, a first refresh state determination circuit and a control signal output circuit,
wherein the first refresh state determination circuit is configured to determine a first refresh state signal and a second refresh state signal according to the row hammer refresh trigger signal, a first clock signal and a first inverted clock signal,
wherein the first clock circuit is configured to determine the first clock signal and the first inverted clock signal according to the first refresh state signal, the initial refresh execution signal and the refresh pulse signal,
wherein the control signal output circuit is configured to determine the preset row hammer refresh signal according to the row hammer refresh trigger signal and the second refresh state signal,
wherein the row hammer refresh instruction instructs to perform word line refresh processing on a first adjacent word line of the target word line and a second adjacent word line of the target word line, and the initial refresh execution signal is configured to indicate a word line refresh processing that occurs for a first time in each refresh period, and the refresh pulse signal is configured to indicate a word line refresh processing that occurs each time in the each refresh period.
