Abstract: An electronic device includes: a non-volatile memory configured to store data including encrypted data; and a digital circuit. The digital circuit includes: a microprocessor configured to access the non-volatile memory and an internal memory; and a decryption circuit arranged on an interconnect network identifying an internal data path for exchanging the data between the non-volatile memory and the microprocessor, and connected to a memory controller of the non-volatile memory for receiving blocks of data from the non-volatile memory, the decryption circuit being configured to: perform a decryption on the fly of blocks of the data read from the non-volatile memory to obtain read decrypted data; generate first decryption masks corresponding to first blocks of data being read from the non-volatile memory at a given read address; and generate second decryption masks corresponding to second blocks of data to be read from the non-volatile memory at a next estimated read address.

Abstract: A delaying element includes a first XOR logic gate and a second XOR logic gate. A first input of the first XOR logic gate defines an input terminal. A first input of the second XOR logic gate is connected to an output of the first XOR logic gate. An output of the second XOR logic gate defines an output terminal. The second inputs of the first and second XOR logic gates are connected to a second input terminal.

Abstract: A logic two-to-one multiplexer includes: two input terminals; one output terminal; a control terminal. Four series-connected two-to-one multiplexers are connected such that a first multiplexer has its inputs connected to the input terminals, a last multiplexer has its output connected to the output terminal, and the other multiplexers have their respective inputs interconnected to the output of the previous multiplexer in the series association. Half of the multiplexers are controlled in reverse with respect to the other half of the multiplexers.

Abstract: A thermally deformable assembly is formed in an integrated-circuit metallization level. The physical behavior of the metal forming the assembly brings the assembly into contact with a stop-forming body when subjected to a temperature change caused by a current flow. A natural rollback to the initial configuration in which the assembly is a certain distance away from the body is prevented. The state or configuration of the assembly is determined by a capacitive reader.
