Claim 11:
12. A refresh circuit, comprising:
a refresh control module configured to receive a refresh command to output a row address refresh signal, the row address refresh signal being outputted a number of times of a preset value each time the refresh command is received; and further configured to receive a temperature signal to adjust the preset value, the higher a temperature represented by the temperature signal, the greater the adjusted preset value;
a row addresser configured to receive the row address refresh signal and output a to-be-refreshed single-row address;
an array refresh device configured to perform a single-row refresh operation according to the single-row address and output a single-row refresh end signal after the end of single-row refresh; and
a switch unit, the refresh control module adjusting the preset value based on the temperature signal when the switch unit is turned on, and the preset value being a default value when the switch unit is turned off;
wherein the switch unit comprises a fuse unit, and the refresh control module receives the temperature signal through the fuse unit.
