Abstract
The invention relates to methods and devices for updating a cache memory in a telecommunications terminal suitable for co-operating with a subscriber identity module. Some implementations of the subscriber identity module may perform operations that include detecting a modification of an elementary file and generating update data associated with the modified elementary file. During a starting stage, the operations may further include receiving a start message from the terminal; receiving a request serving to identity an elementary file for processing; sending the update data associated with the elementary file for processing; and reading the elementary file in compliance with a read command from the terminal. The invention also provides corresponding methods and devices for the terminal, and the corresponding module and terminal.
