Abstract: The invention discloses a device for executing code sequences in a storage medium comprising an integrated circuit (10) capable of executing code sequences and a first memory (12) containing a main programme and optionally other code sequences executable by the integrated circuit, a second non-volatile programmable memory (11) optionally containing code sequences executable by the integrated circuit and a third working memory (14), characterised in that a browser-table contained in the second memory (11) contains at least one field containing a code reference datum. The device includes first means (INS_INT) for: verifying the presence of a code reference, storing in the working memory the address data associated with the code reference and positioning a trap indicator D1 and, second means (INS_ORT) for: testing the trap indicator D1 and, effecting the jump to the address indicated by the contents of the working memory AD_SAUT.
