PURPOSE: A fuse test circuit is provided to determine whether a fuse circuit is normal by comparing a fuse resistor included in the fuse circuit with a fuse resistor set in a system. CONSTITUTION: A fuse test circuit includes a fuse resistor, a comparator(100), and a determining unit(200). The comparator compares the fuse resistor with a first reference resistor and a second reference resistor. The determining unit receives fuse data of the fuse resistor stored in the system and outputs a signal for determining whether the fuse resistor is normal according to the fuse data and the output signal of the comparator.
