    Abstract: A RAM memory integrated circuit, in particular a SRAM memory integrated circuit, includes a matrix of memory cells that are arranged between two bit lines via two access transistors. The bit lines are intended in one case to be discharged and in the other case to be maintained at a high precharge potential during a read operation. The bit line of each column of the matrix that is intended to be maintained at the high precharge potential is produced in the form of at least two partial bit lines. The memory cells of each column are implanted in the form of groups of cells which are alternately connected to one or the other of the partial bit lines, respectively.

    Abstract: A circuit generates a reference voltage that is independent of temperature. The circuit is built on a substrate according to a CMOS technology, and includes a first stage for generating a first current proportional to temperature and a second stage for generating a second current inversely proportional to temperature. These first and second currents are summed in a resistor connected to a voltage distinct from the ground of the first and second stages and formed by the voltage of the substrate on which the circuit is built.

    Abstract: Artifacts of an incident digital image including pixels carrying information are reduced by determining, for certain pixels being considered from the image, displaced pixels. A displaced pixel associated with a pixel being considered is situated at a location that is displaced with respect to the location of the pixel being considered. Substitution information is determined by taking into account the variations between each piece of information carried by pixels situated at locations adjacent to the pixel being considered. The pixel being considered is then selectively replaced by a substitution pixel equal to the displaced pixel or to a combination of the displaced pixel and the pixel being considered, depending on the value of the substitution information.

    Abstract: A process for producing a capacitor integrated into an electronic circuit comprises the formation of a trench in a substrate through a conductive portion similar to an MOS transistor gate. Alternating conductive, insulating and conductive layers are deposited inside the trench T in order to form a lower electrode, a dielectric and an upper electrode of the capacitor, respectively. The conductive portion is used to electrically connect the lower electrode to other electronic components of the circuit without an additional cost with respect to the connection of the circuit transistors.
