Abstract
A semiconductor device includes a fuse array for storing normal fuse data and pattern data through a programming operation, a boot-up control unit suitable for generating an enable signal for enabling an output of the pattern data, and a pattern detection unit suitable for detecting a pattern of the pattern data in response to the enable signal, and generating a detection signal. The fuse array outputs the normal fuse data in response to the detection signal.
Claims18
A semiconductor device comprising:
- a fuse array for storing normal fuse data and pattern data through a programming operation;
- a boot-up control unit suitable for generating an enable signal for enabling an output of the pattern data;
