A monitoring circuit includes: a sampling module, configured to sample an initial address to obtain a monitoring address; a counting module, configured to adjust a counting value of a first counter corresponding to the monitoring address and set a predetermined value for the monitoring address, and a magnitude of the set predetermined value is positively correlated with duration for which the monitoring address is stored in the counting module; and a processing module, configured to compare the counting value of the first counter corresponding to each monitoring address with the predetermined value, where if the counting value of the first counter is greater than or equal to the predetermined value, the monitoring address is retained, and if the counting value of the first counter is less than the predetermined value, the monitoring address is released, and the first counter and the predetermined value corresponding to the monitoring address are reset.
A monitoring circuit, comprising:
A method for refreshing a monitoring circuit, wherein the monitoring circuit comprises a sampling module, a counting module connected to the sampling module, and a processing module connected to the counting module, and wherein the method comprises:
A memory, configured to obtain a word line address to be refreshed by a monitoring circuit located in the memory, wherein the monitoring circuit comprises:
