Abstract: In an embodiment, access transactions of at least one module of a system such as a System-on-Chip (SoC) to one of a plurality of target modules, such as memories, are managed by assigning transactions identifiers subjected to a consistency check. If an input identifier to the check has already been issued for the same given target module, to the related identifier/given target module pair the same input identifier is assigned as a consistent output identifier. If, on the contrary, said input identifier to the check has not been already issued or has already been issued for a target module different from the considered one, to the related identifier/given target module pair a new identifier, different from the input identifier, is assigned as a consistent output identifier.
