Abstract
A fuse circuit includes a program unit and a sensing 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 outputs a sensing output signal based on the program output signal and the sensing output signal indicates whether the program unit is programmed or not. The program unit includes an anti-fuse cell, a selection transistor, a program transistor and a sensing transistor. The anti-fuse cell includes at least two anti-fuse elements which are connected in parallel and are respectively broken down at different levels of a program voltage.
