摘要： An integrated circuit for a smart card may include a universal serial bus (USB) transceiver for communicating with a USB host device, and a microprocessor connected to the USB transceiver and operable in a test mode and a user mode. When in the test mode, the microprocessor may perform a test operation based upon receiving at least one test vendor specific request (VSR) from the USB host device via the at least one USB transceiver. By way of example, the test operation may include scan testing the microprocessor's control logic, detecting a status of at least one buffer and communicating the status to the USB host device, writing test data to at least one designated buffer and sending the test data from the at least one designated buffer to the USB host device, and/or operating with reduced power.

摘要： A fuse for an integrated circuit is constituted by a shallow NP junction, covered with a metal contact, the semiconductor region being not excessively doped. For the blowing of the fuse, the junction is forward biased with a current sufficient to enable a diffusion of metal up to the junction. This short-circuits the junction. The detection is done also by the forward biasing of the junction, but with a low current or a low voltage. The detection can also be done with reverse biasing.

摘要： In a semi-conducting integrated circuit, there is made a light detection circuit, the output signal of which can be used to counter manipulations by dishonest persons who undertake a decapsulation or a removal from the card when the integrated circuit is inserted in a bank type card, or even a depassivation of the upper protective layer of this integrated circuit, in order to reveal the secret functioning of the circuit or to modify its characteristics. The detector comprises a current generator delivering a current of limited intensity which flows into a reversed biased electronic junction. When the junction is subjected to light, the reverse current that can be allowed into the junction increases. Since the current generator is not capable of putting through stronger current, the voltage at the terminals of the junction drops. This drop in voltage is used as information that reveals the illumination.
