The present invention relates to a semiconductor device having a fuse array structure. The semiconductor device comprises: a fuse array in which a plurality of fuses are arranged in an array shape wherein data of set values are programmed in some of the fuses; a determination block configured to read the data programmed in the fuses set based on the level of a read reference voltage during a boot-up preparation section and to determine whether or not a read value is the same as a predetermined value; and a level control block configured to adjust the level of the read reference voltage in response to a determined result of the determination block during the boot-up preparation section. |
