Abstract: PROBLEM TO BE SOLVED: To provide a collision prevention method for identifying and selecting a plurality of non-contact electronic modules by means of a simple structure and to provide the non-contact electronic module. SOLUTION: In advance of communication between a terminal 19 and a plurality of non-contact electronic modules 10, the respective modules 10 generate random identification numbers ID. During a time slot varied according to the identification numbers, the module 10 responds to a general or auxiliary identification request, and the module 10, which is not selected on receipt of the auxiliary identification request PCALL16, generates new random identification number. While the time slot is varied according to this identification number, a time slot of the unselected module 10 complying with the auxiliary identification request is prevented from being equalized to that of the module 10 complying with the previous auxiliary identification request.

Abstract: The buffer circuit comprises the transfer means including a switch (SW1) and two inverter gates (11,12) connected in series, the inhibition block (IB) for inhibiting the transfer means during all or part of the pulse rise and decay times, that is in the intervals (t1-t2) and (t3-t4), and the storage means including a switch (SW2) and two inverter gates (13,14) for maintaining the output at a logic value which was present during the periods of inhibition. The switch (SW1) is controlled by the inhibition signal (INHIB) delivered by the inhibition block (IB). The inhibition block contains two asymmetric inverter gates (15,16) with low and high threshold voltages (VtI,Vth), and an exclusive-OR or NOT exclusive-OR (NXOR) gate receiving the signals (Sa,Sb) delivered by the asymmetric inverter gates. The inverter gates (11,13) form a memory cell, and the switch (SW2) is controlled by the inverse inhibition signal (/INHIB). An integrated circuit such as serial input/output memory store receives a clock signal by the intermediary of the buffer circuit.

Abstract: L'invention concerne un procédé de gestion de l'accès à un espace mémoire (UMEM) partageable par plusieurs utilisateurs, au moyen de mots de passe, comprenant les étapes consistant à : définir un nombre maximal de mots de passe (pwl-pw3), prévoir une zone de stockage des mots de passe (PZ), diviser l'espace mémoire partageable (UMEM) en une pluralité de blocs (B0-Bn) en nombre supérieur au nombre maximal de mots de passe (pw1-pw3), prévoir dans chaque bloc un champ de paramétrage (PD0-PDn) de la protection du bloc, prévoir dans chaque champ de paramétrage (PD0-PDn) un index binaire (IDX) de taille inférieure à la taille d'un mot de passe et désignant un mot de passe (pwl-pw3) affecté à la protection du bloc, et attribuer à chaque bloc des droits d'accès nécessitant la présentation d'un mot de passe correspondant au mot de passe désigné par l'index (IDX) présent dans le champ de paramétrage (PD0-PDn) du bloc. Application notamment au circuits intégrés multi-utilisateurs.
