Abstract: An EEPROM cell is described as having a screening metal structure formed of preference in the first metal layer and located in substantial overlaying relationship at the floating gate terminal. This defeats the possibility of anomalous readings being obtained by measuring the amount of charge on the floating gate terminal. An additional screening metal structure, to be formed in the third and following metal layers, may be provided to fully overlie the cell and provide additional protection against anomalous readings.

Abstract: In a memory, a zone descriptor contains authorizations to act which may pertain to actions of reading, writing and erasure and which concerns memory words of a zone of the memory controlled by this descriptor. The zone descriptor also has an information element indicating the length of the memory zone by including the address of the next descriptor. An internal zone control signal is produced in order to store a mode of management of the memory zone and, an address corresponding to the end of the zone. The end of zone address is then compared with the addresses delivered by an address counter. A modification of the stored information is prompted when the end of a zone is reached.

Abstract: A memory device may include a memory plane including a group of memory cells configured to store a block of bits including data bits and parity bits, and a detector for detecting a fault injection including a reader to read each bit, and a first checker to perform, when reading a block, a parity check based on the read value of each data and parity bit. The memory plane may include reference memory cells arranged between some of the memory cells to create packets of m memory cells. Each reference memory cell may store a reference bit and each packet of m memory cells may store m bits of the associated block, when m is greater than 1, with different parities. The detector may further include a second checker to perform, when reading the block, a check on the value of each reference bit.

Abstract: A method processes parallel electrical signals, using parallel processing circuits that process successive cycles of electrical signals according to a rule for allocating electrical signals to the processing circuits. The method comprises, between the processing cycles, a step of modifying the rule for allocating electrical signals to the processing circuits, so that a processing circuit processes electrical signals of different ranks during different processing cycles. The method can be applied particularly to secure a memory during read phases of the memory and of an integrated circuit with a microprocessor using such a memory.
