HIGH VOLTAGE PUMP SYSTEM FOR PROGRAMMING FUSES

摘要

A voltage pump system for programming fuses on a semiconductor chip, in accordance with the present invention, includes a first pump system (12) employing a supply voltage (VDD) of the semiconductor chip as an input. The first pump system supplies an output voltage (VPP) higher than the supply voltage on a first output line (16) without raising the supply voltage of the semiconductor chip. A second pump system (20) includes an input connected to the first output. The second pump system supplies an output voltage (VFuse) sufficient for programming electrical fuses on the semiconductor chip.
