Abstract

The semiconductor system includes a controller and a semiconductor device. The controller outputs commands and receives an output datum to discriminate whether at least one of a plurality of fuse cells abnormally operates. The semiconductor device compares logic levels of a plurality of fuse data generated from the plurality of fuse cells with each other, thereby generating a flag signal enabled when at least one of the logic levels of the plurality of fuse data is different from the other logic levels while a boot-up operation is executed according to a combination of the commands. In addition, the semiconductor device outputs the flag signal as the output datum while a read operation is executed according to a combination of the commands.
