    Abstract: The present invention relates to a system and a method of memory management of data consistency relating to a main memory (4) accessible by at least two processors (1, 2), as well as an associated multiprocessor network. The management system comprises an assembly for management of shared access of the processors to a common area (9) of the main memory, referred to as the exchanges area, at least one copy module (12, 13) intended for performing a data copy between at least one first processor comprising at least one cache memory and the exchanges area and at least one transfer module (12, 13) intended for performing a transfer of data between the exchanges area and at least one second processor. Triggering means controlled by the second processors trigger the copy modules and transfer modules when the first processors submit requests involving transfers of data between the first and second processors.
