摘要

The present invention relates to a method and system for controlling a number of writing cycles supported by a cell or portion (11) of a non volatile memory (4) of an IC Card (10), including the steps of counting write accesses to the memory portion (11) and storing a first counter (21) of the write accesses in another portion (21) of said non volatile memory (4). The method comprises coupling the first counter (21) to a second counter or value (31) associated to a RAM (4) (Random Access Memory) of the IC Card (10), wherein the second counter or value (31) is updated each time the write accesses occur on said cell or portion (11) to be controlled and the first counter (21) is written in the another portion of non volatile memory only when the second counter or value (21) corresponds to a predetermined value.
