Abstract
Process for reclaiming storage spaces in a microcircuit card when they are no longer used by the references of the system. Each storage space (EM,-EM,) is provided with a header (E,-E,) containing a number of references representative at any moment of a plurality of references requesting the data of the corresponding storage space. The headers form the object of chaining (Ch) and a storage space the number of references of which has been reduced to zero can be re-allocated. Under certain conditions, available and adjacent storage spaces can be merged.
