Abstract:
Memory circuitry includes memory components operable in response to first edges of an internal clock.

A regulation device may be configured for regulating an output voltage of a charge pump voltage generator. The regulation device may include a first regulation loop capable of generating and delivering, to a first input of the voltage generator, an input voltage depending on the difference between the output voltage and a first reference voltage. The regulating device may also include a charger capable of generating and delivering, to a second input of the voltage generator, a substantially constant charge voltage. An electronic device may include the regulation device.
Abstract:
The generation of a Hall voltage within a semiconductor film of an integrated Hall effect sensor uses the flow of a current within the semiconductor film when subjected to a magnetic field. The film is disposed on top of an insulating layer, referred to as buried layer, which is itself disposed on top of a carrier substrate containing a buried electrode that is situated under the insulating layer. A biasing voltage is applied to the buried electrode.

Abstract:
A memory circuit for an Aho-Corasick type character recognition automaton uses a node tree for recognizing predetermined strings of characters in an incoming data stream. The recognization is based upon successive transitions in the node tree stored in memory in which each node corresponds to a recognized sequence of a character string. At least part of the nodes are related to a consecutive node by a valid transition, from an initial state to terminal states, with each one corresponding to a recognized character string This memory circuit includes first sets of consecutive memory addresses defining respectively strings of consecutive nodes accessible sequentially during successive transitions to a terminal state, and second sets of memory addresses defining multiple nodes each pointing to several states.

Abstract:
A three-dimensional integrated structure is fabricated by assembling at least two parts together, wherein each part contains at least one metallic line covered with a covering region and having a free side. A cavity is formed in the covering region of each part, that cavity opening onto the metallic line. The two parts are joined together with the free sides facing each other and the cavities in each covering region aligned with each other. The metallic lines are then electrically joined to each other through an electromigration of the metal within at least one of the metallic lines, the electromigrated material filling the aligned cavities.

An integrated circuit is produced on a bulk semiconductor substrate in a given CMOS technology and includes a semiconductor device for protection against electrostatic discharges. The semiconductor device has a doublet of floating-gate thyristors coupled in parallel and head-to-tail. Each thyristor has a pair of electrode regions. The two thyristors respectively have two separate gates and a common semiconductor gate region. The product of the current gains of the two transistors of each thyristor is greater than 1. Each electrode region of at least one of the thyristors has a dimension, measured perpendicularly to the spacing direction of the two electrodes of the corresponding pair, which is adjusted so as to impart to the thyristor an intrinsic triggering voltage less than the breakdown voltage of a transistor to be protected, and produced in the CMOS technology.
