ABSTRACT:
A method reads a datum saved in a memory by selecting an address of the memory in which the datum to be read is saved, reading the datum in the memory at the selected address, saving the datum read in a storage space, and when the memory is not being accessed by a CPU, reading the datum in the memory, reading the datum saved in the storage space, and activating an error signal if the datum read in the memory is different from the datum saved. The method can be applied particularly to the protection of smart card integrated circuits.
