Abstract
In an integrated circuit provided with a memory including redundancy elements and fuses for switching-over to the redundancy elements, a supplementary terminal for receiving a high voltage is connected to all the fuses and to a circuit which generates low voltage at the time of programming of the memory and which is capable of presenting high impedance when the high voltage is applied, with the result that the entire current flows through the fuses selected for blowout.
