  • Publication number: 20080049524
    Abstract: A memory cell stores information in the form of a first logic level and a second logic level that are complementary to each other. The memory cell includes a first storage circuit and a second storage circuit for storing the first logic level and the second logic level. The first and second storage circuits each have a respective input and output. An isolation circuit provides electrical isolation of the input of the first storage device from the output of the second storage device, except during access to the first and second storage circuits.

  • Patent number: 7196959
    Abstract: A multivibrator includes a first data transfer port that receives, as input, multivibrator input data. A first, master, latch cell is connected on the output side of the first transfer port. A second, slave, latch cell is connected thereto through a second data transfer port placed between the first and second latch cells. Each latch cell includes a set of redundant data storage nodes for storing information in at least one pair of complementary nodes and circuitry for restoring information in its initial state, after a current or voltage spike has modified the information in one of the nodes of the said pair, on the basis of the information stored in the other node. The nodes of each pair are implanted opposite one another in a zone of a substrate defining the latch cell.

  • Publication number: 20060258066
    Abstract: An integrated electronic circuit comprises active components disposed on the surface of a substrate and connected by electrical connections disposed within a metallization level. A dielectric material situated between the surface of the substrate and the metallization level, or in the metallization level, has a locally higher value of dielectric permittivity so as to selectively increase a capacitance between certain portions of the active components or of the connections. An electrical state of the circuit in operation is then stabilized, thanks to a higher electrical charge carried by the portions of the active components or of the connections whose capacitance is enhanced. The circuit can be a static random access memory cell.

  • Publication number: 20040252571
    Abstract: A circuit (200) for protection against voltage or current spikes receives an initial clock signal (CI) and transmits at least one resultant clock signal (CN1, CN2, CP1, CP2) to a downstream circuit. This resultant clock signal is inactive if a random voltage or current spike appears upstream. This averts the possibility of disturbing the operation of the downstream circuit. Application to the protection of clock circuits for integrated circuits.
