Semiconductor chip for application in an integrated circuit generates a programming voltage on the chip while using a sensor/detector in a circuit to verify the creation of the voltage

摘要

A circuit structure has a metal oxide semiconductor transistor (1) or an XOR gate, with which a signal (S) is emitted to a control unit if a programming voltage (HV) is not correct. This makes it possible to recognize technical defects and to prevent deliberate attacks on the functionality of a chip. An Independent claim is also included for a circuit structure for verifying a programming voltage on an integrated circuit chip.
