Abstract
Semiconductor systems are provided. The semiconductor system includes a controller and a semiconductor device. The controller generates a power voltage signal. The semiconductor device generates a power-up signal in response to the power voltage signal, generates a first selection pulse, a second selection pulse and an initialization pulse signal, generates a first fuse signal for controlling an internal operation according to a cut state of a first fuse, and generates a second fuse signal for controlling the internal operation according to a cut state of a second fuse.
