An efuse circuit adapted for a memory device is provided. The efuse circuit includes a plurality of efuse sets and a control circuit. Each of the plurality of efuse sets includes a plurality of efuses. When a power is turned on, the control circuit detects each of the plurality of efuse sets to generate a detection signal. The control circuit determines whether the efuses of each of the efuse sets are burned according to the detection signal to determine whether to perform a burn operation on the plurality of efuses. When the control circuit determines that at least one of the plurality of efuses is a burned efuse according to the detection signal, the control circuit latches a write data of at least one burned efuse and disables an overwrite operation on the efuse set to which the at least one burned efuse belongs.
