Abstract
The present invention relates to a process and a device for modifying code sequences written into a first memory ( ) of a medium. A central processing unit ( ) executes code sequences and the first memory contains a main program comprising at least one code sequence executable by the central processing unit ( ). The first memory also comprises a second, programmable nonvolatile memory ( ), and a third working memory ( ). A branch table TAB_DER contained in the second programmable memory contains at least one field containing reference data for a new code sequence stored in one of the memories. Branching instructions allow a deferred branch from the executed code sequence to the new code sequence written into one of the three memories. Instructions in the new code sequence allow the return to a point of the code sequence executed before the branch.
