Abstract
Abstract The invention relates to a method for management of an electronic memory representing predetermined homogenous units, of the generic type comprising inscribing in memory a stop indicating the balance at the end of a transaction. In this method, the memory is divided into elements including a non-specific number of cells, and at the time of a transaction, the search for the stop is performed by determining at the outset the element in which it is located, and then the precise position that it occupies in this element. A new stop is then inscribed starting at the position of this previous stop, and then this previous stop is neutralized so that it will be ignored in later transactions. The invention is applicable to electronic payment devices.
