Abstract
A semiconductor device includes an internal command generation circuit suitable for generating a first internal command, a second internal command, and a third internal command based on a command/address signal. The semiconductor device also includes a driving signal generation circuit suitable for enabling a fuse driving signal for reading fuse data from a nonvolatile memory circuit, where the fuse signal is enabled while the second internal command is inputted a predetermined number of times. Further included is an output circuit suitable for outputting the fuse data in response to the third internal command.
