Abstract
A method for storing of a plurality of data blocks in a digital rewritable memory of semiconductors controlled by a memory manager and includes the steps of: randomly determining an available area; and storing the data block in the area determined in the determining step. This method of data storage is preferably applied to chip cards and to similar electronic modules. It prevents the reproduction of the functionalities of the card after an analysis of the contents of the memory. Furthermore, it assures a better distribution of the wearing of the memory.
