摘要

The present invention relates to the field of the management of memory writes to an information processing device and more precisely to a method of writing a set of data in a unitary and coherent manner. The invention, although of more general scope, applies more particularly in the field of chip cards. There is described a method of writing one or more data to the memory of an information processing device which comprises a step of copying a so-called original memory block comprising the data to be written to a so-called backup memory block. The data writing step is then carried out in the original memory block or in the backup memory block. It is then always possible to return if necessary to the values of the original data if the writing phase fails.
