CHIP OR SYSTEM-BOX PROTECTION USING THE GMI EFFECT

摘要

Device (100) of the chip or electronic system package type, comprising at least one protection element (114) of at least a part of at least one face (116) of the device, said protection element comprising at least: - a device attack detection element (118) comprising at least one electrically conductive material with GMI effect, and - a magnetic field emitter to which said electrically conductive material with GMI effect is intended to be subjected, and in which the effect GMI is intended to be obtained in the electrically conductive material with GMI effect when it is traversed by an alternating electric current of excitation and subjected to the magnetic field of the emitter (126) of magnetic field.
