Abstract
A memory is secured against an error injection during the reading of a datum. The memory includes: means for reading a reference datum in the memory during a phase of reading a datum stored in the memory; means for comparing the reference datum read with an expected value; and means for generating an error signal if the datum read is different from the expected value. Application is provided particularly but not exclusively to the protection of memories integrated into smart cards.
