    Abstract: A method for managing the access to a memory space shareable by several users, by using passwords, comprises: defining a maximum number of passwords, providing a password storage zone, dividing the shareable memory space into a plurality of blocks greater in number than the maximum number of passwords, providing in each block a parameterization field for parameterizing the protection of the block, providing in each parameterization field a binary index smaller in size than a password and designating a password assigned to the protection of the block, and allocating, to each block, access rights requiring a password to be presented corresponding to the password designated by the index present in the block parameterization field. Application is provided particularly but not exclusively to multi-user integrated circuits.

    Abstract: An anti-collision method to identify and select contactless electronic modules (MDL) by a terminal is provided. A module may generate a random identification number prior to a communication, and respond to a general or complementary identification request on a time slot that varies according to its identification number. A non-selected module may generate a new random identification number when it receives a complementary identification request. Thus, the time slot of a non-selected module provided in response to a complementary identification request is not statistically the same as its time slot in response to a previous identification request, and it varies according to its identification number (ID).

    Abstract: An inductive coupling reader includes a passive interface circuit for modulating the impedance of an antenna circuit and extracting from the antenna circuit a data signal and a RF clock signal, and circuitry for coupling the reader to a removable security module. The reader includes an emulation circuit for opening a RF transmission channel with another reader, a non-removable electrical link linking the emulation circuit to the passive interface circuit, by which the data signal and the RF clock signal are supplied to the emulation circuit, and a data bus clocked by a bus clock signal having a frequency inferior to the frequency of the RF clock signal, for linking the emulation circuit to the removable security module. The reader has low electrical consumption.

    Abstract: An electrically erasable and programmable non-volatile semiconductor memory includes memory registers that are addressable individually or by blocks. The memory also has a protection register in which a protection word can be written. The protection word has a given number of bits that encode a boundary address of the memory register or a block of memory registers. The boundary address divides the memory space into an upper zone and a lower zone. The protection word also has a zone bit whose value determines which of the two zones of the memory is to be write protectable.
