Abstract
A voltage pump system for programming fuses on a semiconductor chip, in accordance with the present invention, includes a first pump system employing a supply voltage of the semiconductor chip as an input. The first pump system supplies an output voltage higher than the supply voltage on a first output line without raising the supply voltage of the semiconductor chip. A second pump system includes an input connected to the first output. The second pump system supplies an output voltage sufficient for programming electrical fuses on the semiconductor chip.
