ABSTRACT:
A redundant circuit for a semiconductor device including a fuse program means producing a control signal determining whether or not a chip is normal; a high-voltage generating means producing a first voltage or second voltage according to a control signal from the fuse program means; and an on-chip redundant decoding means driven by the first voltage or second voltage produced from the high-voltage generating means. In case that the chip is normal, the high-voltage generating means generates the first voltage, and in case that the chip fails, the high-voltage generating means produces the second voltage. The first voltage is an output voltage from the high-voltage generating means, and the second voltage is an output voltage higher than the first voltage.
