Abstract
This microcircuit card includes means for detecting an attack on the card, command means () capable of charging a charge pump () capable of applying a programming voltage (UP) to command a write operation into a cell () of a nonvolatile memory when an attack is detected, and a capacitor () arranged so as to be supplied with power during normal operation and to supply said charge pump () with power only when an attack is detected. The card () being characterized in that said capacitor () also supplies power to the command means () when an attack is detected.
