Abstract:
A semiconductor device includes: a fuse set unit including a plurality of fuse sets, each fuse set including one or more address fuses and an enable fuse; a rupture control unit suitable for controlling the enable fuse of a selected fuse set to be programmed after the address fuses of the selected fuse set is programmed, during a program operation; a cell data verify unit suitable for repeatedly performing a verify and rupture operation on the selected fuse set during the program operation, determining whether read data from the selected fuse set is identical to target data corresponding to a rupture address through a final verify operation, and outputting fail information; and a fuse set control unit suitable for controlling the program operation to be performed on a different fuse set after the program operation on the selected fuse set is terminated, in response to the fail information.
