Abstract
The semiconductor device includes a power control signal generator, a fuse controller and a fuse array portion. The power control signal generator generates a power control signal enabled during a predetermined period from a termination moment of a power-up period and enabled in response to a test mode signal. The fuse controller generates a boot-up signal enabled if a reboot-up signal is inputted during an enablement period of the power control signal. The fuse controller also generates a fuse reset signal enabled if a reset signal is inputted after a clock training operation. The fuse array portion generates a plurality of fuse data initialized if the fuse reset signal is enabled. The plurality of fuse data are programmed according to electrical open/short states of fuses in response to the power control signal.
