Abstract
A fuse circuit includes a program unit, a sensing unit and a control unit. The program unit is programmed in response to a program signal, and outputs a program output signal in response to a sensing enable signal. The sensing unit includes a variable resistor unit that has a resistance that varies based on a control signal, and generates a sensing output signal based on the resistance of the variable resistor unit and the program output signal. The control unit generates the control signal having a value changed depending on operation modes, and performs a verification operation with respect to the program unit based on the sensing output signal to generate a verification result. The program unit may be re-programmed based on the verification result.
