Abstract: PURPOSE: A fuse circuit and method thereof are provided to improve reliability of electrically the programmable fuse. CONSTITUTION: When resistive value of a first fuse unit(102) is smaller than that of a second fuse unit(104), voltage levels of nodes(ND10,ND20) of a fuse circuit(200) are determined by the size of capacitive parasitic loading of each node. When a control pulse signal(MRS1) transits a low level to a high level, NMOS transistors(114,116) are turn-on. Thereby, fine voltage differences due to resistive difference of the fuse units(102,104) create between the nodes(ND10,ND20) according to a plurality of PMOS and NMOS transistors(106,108,114,116) used as current sense amplifier circuits. The current applied to the first and second fuse units(102,104) having difference resistive value is constantly discharged via the NMOS transistors(114,116) having same discharging capability regardless of the size of capacitive parasitic loading of the nodes(ND10,ND20). Thereby, the voltage of the first node(ND10) is highly set compared to the voltage of the second node(ND20).
