  • Patent number: 8461907
    Abstract: A semiconductor device includes a signal output unit, and a decision unit. The signal output unit includes m (?2) pieces of fuses, a NAND gate, resistance elements, and an output terminal. The decision unit decides whether n or more pieces (m?n?2) of fuses are disconnected out of the m pieces of fuses included in the signal output unit, and outputs the result of a decision. When m=n=2, the decision unit is constituted of a NOR gate having two input terminals connected to a respective end of the fuses. Thus, a H-level potential signal is output at an output terminal of the NOR gate when the decision result is affirmative. On the other hand, when the decision result is negative, a L-level potential signal is output at the output terminal.
