  • Patent number: 10236066
    Abstract: A non-volatile data memory space for a range of user addresses is provided by means of a range of non-volatile flash memory locations for writing data. The range of flash memory locations for writing data is larger (e.g., 4 KB v. 100 B) than the range of user addresses. Data for a same user address may thus be written in different flash memory locations in a range of flash memory locations with data storage endurance correspondingly improved.

  • Patent number: 10236865
    Abstract: An attenuator having an impedance that is controllable by a first setpoint signal is coupled to a transmission line. A matching circuit having an impedance that is controllable by a second setpoint signal is also coupled to the transmission line.

  • Patent number: 10237725
    Abstract: A receiver for digital signals includes a radiofrequency stage. A feedback loop controls a variable attenuation resistance applied to a modulated radiofrequency signal passing through the radiofrequency stage as a function of a comparison of an amplitude of the modulated radiofrequency signal with a reference value. A baseband stage includes an RC network cascaded to the radiofrequency stage and coupled to a baseband detector that generates the baseband signal. The feedback loop includes a circuit for detecting a range of variation of the comparison.

  • Publication number: 20190081011
    Abstract: An electronic integrated circuit includes a semiconductor substrate having a rear face. A device for detecting a thinning of the semiconductor substrate via its rear face is formed by a p-n junction that is biased into conduction. Thinning of the substrate is detected by monitoring a current flowing through the p-n junction, and comparing that current to a threshold. In the event the compared current indicates no thinning of the semiconductor substrate, the circuitry for biasing and comparing is deactivated.

  • Publication number: 20190081079
    Abstract: A tensile strained silicon layer is patterned to form a first group of fins in a first substrate area and a second group of fins in a second substrate area. The second group of fins is covered with a tensile strained material, and an anneal is performed to relax the tensile strained silicon semiconductor material in the second group of fins and produce relaxed silicon semiconductor fins in the second area. The first group of fins is covered with a mask, and silicon-germanium material is provided on the relaxed silicon semiconductor fins. Germanium from the silicon germanium material is then driven into the relaxed silicon semiconductor fins to produce compressive strained silicon-germanium semiconductor fins in the second substrate area (from which p-channel finFET devices are formed). The mask is removed to reveal tensile strained silicon semiconductor fins in the first substrate area (from which n-channel finFET devices are formed).

  • Publication number: 20190081004
    Abstract: Many integrated circuit die are fabricated on a wafer. Each die includes integrated functional circuitry with an array of fuse elements that are visible to optical inspection. An electrical wafer sort is performed to test the integrated functional circuitry of each die. The array of fuse elements for each die on the wafer are programmed through the electrical wafer sort process with data bits defining a die identification that specifies a location of the die on the wafer. The die is then encapsulated in a package. In the event of package failure, a decapsulation is performed to access the die. Optical inspection of the array of fuse elements is then made to extract the die identification.
