Abstract
A method is for executing n data updates in an IC Card which has memory pages supporting m erase operations per page, with m<n. The method includes the step of allocating a cyclic elementary file including N records, each record associated to a memory page of the IC Card, and the cyclic elementary file indexing a less recently updated record which is erased before writing data to be updated.
