Abstract: A cryptographic circuit performs a substitution operation of a cryptographic algorithm. For each substitution operation of the cryptographic algorithm, a series of substitution operations are performed by the cryptographic circuit. One of the substitution operations of the series is a real substitution operation corresponding to the substitution operation of the cryptographic algorithm. One or more other substitution operations of the series are dummy substitution operations. A position of the real substitution operation in said series is selected randomly.

Abstract: A start-up phase of a phase lock loop (PLL) circuit includes supplying, by a phase comparator, of control pulses during which an output signal frequency of an oscillator increases. The increase includes an application of a pre-charge current at the oscillator input. A determination is made of a time variation of the output signal frequency. At least one adjustment is made of the intensity of the pre-charge current depending on the at least one determined time variation so as to approach a reference time variation.

Abstract: An embodiment method for converting an initial digital image into a converted digital image, electronic chip, system and computer program product are disclosed, the initial digital image comprising a set of pixels, the pixels being associated respectively with colors, the initial digital image being acquired by an acquisition device, and the converted digital image able to be used by a neural network. The embodiment method comprises redimensioning of the initial digital image in order to obtain an intermediate digital image, the redimensioning being carried out by a reduction in the number of pixels of the initial image, modification of a format of one of the pixels of the intermediate digital image in order to obtain a converted digital image, the modification being carried out, after the redimensioning, by increasing the number of bits used to represent the color of the pixel.

Abstract: A first integrated circuit chip is assembled to a second integrated circuit chip with a back-to-back surface relationship. The back surfaces of the integrated circuit chips are attached to each other using one or more of an adhesive, solder or molecular bonding. The back surface of at least one the integrated circuit chips is processed to include at least one of a trench, a cavity or a saw cut.

Abstract: An electronic chip includes a chip core including an input terminal, an output terminal, an external pad, and an input-output circuit coupled to the chip core and the external pad. The input-output circuit includes an enable terminal coupled to the chip core, a connection terminal coupled to the external pad, a switchable diode device coupled between a supply voltage and a reference voltage, and a levelling circuit. The switchable diode device is coupled to the connection terminal and the enable terminal and is configured to operate as a diode in response to a control signal in a first state applied to the enable terminal and to operate as an open circuit in response to the control signal in a second state applied to the enable terminal. The levelling circuit is coupled to the connection terminal, the input terminal of the chip core, and the output terminal of the chip core.

Abstract: A datum is written to a memory, by splitting a binary word, representative of the datum and an error correcting or detecting code, into a first part and a second part. The first part is written at a logical address in a first memory circuit. The second part is written at the logical address in a second memory circuit. The error correcting or detecting code is dependent on both the datum and the logical address.

Abstract: A process for fabricating an integrated circuit includes the fabrication of a first transistor and a floating-gate transistor. The fabrication process for the first transistor and the floating-gate transistor utilizes a common step of forming a dielectric layer. This dielectric layer is configured to form a tunnel-dielectric layer of the floating-gate transistor (which allows transfer of charge via the Fowler-Nordheim effect) and to form a gate-dielectric layer of the first transistor.

Abstract: According to one aspect, a method for determining, for a memory allocation, placements in a memory area of data blocks generated by a neural network, comprises a development of an initial sequence of placements of blocks, each placement being selected from several possible placements, the initial sequence being defined as a candidate sequence, a development of at least one modified sequence of placements from a replacement of a given placement of the initial sequence by a memorized unselected placement, and, if the planned size of the memory area obtained by this modified sequence is less than that of the memory area of the candidate sequence, then this modified sequence becomes the candidate sequence, the placements of the blocks for the allocation being those of the placement sequence defined as a candidate sequence once each modified sequence has been developed.
