The invention is a method of analyzing the wear of a non volatile memory embedded in a secure electronic token. A set of events are intended to generate writing and/or erasing operations in said memory. The token comprises a buffer. The method comprises the following steps: each time an event belonging to said set occurs, generating a data which reflects the event and storing said data in the buffer, sending the buffer to a remote machine, analyzing the buffer to determine the wear of the memory.
