  • Patent number: 7391661
    Abstract: A memory is organized with many memory subspaces (db<i>) each including their own read-out circuit (SA<i>). At least one redundant column (Blred) is provided within each subspace in order to compensate for at least one defective column of said subspace. A memory controller is provided for interacting with the memory via a write bus (TD) and a read bus (Q). The memory controller generates a signal (TD<i>) for enabling the redundant column. This signal is provided so as to be conveyed to the read-out circuits of the memory to which the write bus (TD) is connected. Thus, one enables, via the read-out circuits, the redundant column of the memory subspaces which are associated with a defective column address.

  • Patent number: 7391449
    Abstract: For each current image output from a pixel matrix, the digital words relative to at least one masked line of the matrix are processed to generate a current correction digital code. From this code, a black level compensation signal is generated and applied as an offset control on pixel signal amplification. If the current correct digital code does not differ from the code calculated for a previous image output by a predetermined amount, then the code for the previous image is instead used to generate the black level compensation signal.

    Abstract: An acoustic resonator assembly includes a layer of high-acoustic-impedance material and a layer of low-acoustic-impedance material made of a low-electrical-permittivity material. This assembly may support the resonator over an interconnect layer or act as a decoupling assembly between two active elements of the resonator. The assembly may alternatively include three low-acoustic impedance layers. Alternatively, the assembly may include three acoustic impedance layers wherein two of the layers are low acoustic impedance layers and the third layer has a higher acoustic impedance than the first two or alternatively is a high-acoustic impedance layer.

  • Patent number: 7392332
    Abstract: A dedicated processing module includes an input for data to be processed and an output for processed data. A block input and a block output are also included. A processing component for the module performs a digital processing operation on the data present at the data input and applies the processed data at the data output. The processor may further generate a block request. A control device within the module reproduces, at the block output, a block request applied to the block input or generated by the processing component. The control device thus may operate to block the application of processed data at the data output upon receipt of a block request at the block input. Two or more dedicated processing modules may be connected in series with each other to form a processing flow chain with the data output of one module connected to the data input of a subsequent module. Additionally, the block output of the subsequent module is connected to the block input of the preceding module.

  • Publication number: 20080142929
    Abstract: A porous dielectric element is produced by forming a first dielectric and a second dielectric. The second dielectric is dispersed in the first dielectric. The second dielectric is then removed from the second dielectric by using a chemical dissolution. The removal of the second dielectric from the first dielectric leaves pores in the first dielectric. The pores, which are filled with air, improves the overall dielectric constant of the resulting dielectric element.

  • Patent number: 7388418
    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.
