Process implemented in an integrated circuit module, corresponding integrated circuit module, system comprising such a module and corresponding computer program

Integrated-circuit module, comprising a communication interface and a processor configured to access a non-volatile memory wherein a plurality of execution-context-defining software applications are stored, adapted to be executed by a processor for communication via the communication interface, and to access a volatile memory configured to store execution data of a software application currently being executed, the module being configured to, on reception of a command on Its communication interface, the plurality of software applications comprising a first software application currently being executed and a second software application previously suspended,

• a. suspend execution of the first software application currently being executed, the suspension comprising
• i. saving the content of the volatile memory in a first backup location of the non-volatile memory,
• ii. stopping the execution of the first software application,
• b. resume the previously suspended execution of the second software application comprising
• i. transferring into the volatile memory, from a second backup location of the non-volatile memory, execution data relating to the previously suspended execution of the second software application, and
• ii. executing the second software application, the module being configured to delete the content of the second backup location following resumption of execution of the second software application.
