Abstract (en)
[origin: FR2764716A1] The invention concerns a device for modifying code sequences written in a medium memory (2) comprising a central unit (1), said memory containing a main programme executable by the central unit (1) which also comprises a second non-volatile programmable memory (3), and a third working memory.(4). The invention is characterised in that a rerouting table TAB_DER contained in the second programmable memory contains at least one field containing a new code sequence reference data, rerouting means for delayed rerouting of the executed code sequence towards the new code sequence written in one of the three memories and means in the new code sequence for returning to a point of the sequence before rerouting.
