HACKING DETECTING DEVICE, INTEGRATED CIRCUIT AND METHOD OF DETECTING A HACKING ATTEMPT

摘要

A hacking detecting device includes a metal line capacitor, a charge providing unit, a charge storing unit and a hacking deciding unit. The metal line capacitor has a first metal line and a second metal line. The charge providing unit periodically charges the metal line capacitor. The charge storing unit accumulates charges periodically stored in the metal line capacitor, and generates an output voltage corresponding to an amount of the accumulated charges. The hacking deciding unit determines whether the metal line capacitor is exposed based on the output voltage of the charge storing unit.
