Abstract: A semiconductor circuit has at least one generator fuse for setting a supply voltage and at least one redundancy fuse for activating a redundancy element. A first read-out device is provided for reading out the generator fuse and a second read-out device reads out the redundancy fuse. The first read-out device is configured to read out the generator fuse at a first instant, and the second read-out device is configured to read out the redundancy fuse at a second instant.

Abstract: The power supply to the integrated circuit (1) consists of a controller (4), control circuit (3) and voltage pump circuit (2). Controlled switching of a first (C1) and second (C22) capacitors using switching transistors (T11,T12,T21,T22) pumps the supply voltage (V1) to a higher level (VPP) required to operate the integrated circuit. When the integrated circuit is in a stand-by mode the second capacitor is rendered inoperative to reduce the output voltage.
