  • Publication number: 20230318589
    Abstract: A first input node receives a first input signal and a second input node receives a second input signal. The first and second input signals are in phase quadrature. An edge detector circuit senses the first input signal and produces a pulsed signal indicative of edges detected in the first input signal. A pulse skip and reset circuit senses the pulsed signal and the second input signal, and produces a reset signal indicative of pulses detected in the pulsed signal while the second input signal is de-asserted. A sampling circuit senses the second input signal and the reset signal, and produces an output signal that is deasserted in response to assertion of the second input signal and is asserted in response to a pulse being detected in the reset signal.

  • Publication number: 20230317637
    Abstract: An integrated circuit memory includes a state transistor having a floating gate which stores a respective data value. A device for protecting the data stored in the memory includes a capacitive structure having a first electrically-conducting body coupled to the floating gate of the state transistor, a dielectric body, and a second electrically-conducting body coupled to a ground terminal. The dielectric body is configured, if an aqueous solution is brought into contact with the dielectric body, to electrically couple the floating gate and the ground terminal so as to modify the charge on the floating gate and to lose the corresponding data. Otherwise, the dielectric body is configured to electrically isolate the floating gate and the ground terminal.

  • Publication number: 20230291216
    Abstract: A circuit monitors a first voltage delivered by a battery. The monitored first voltage is compared with a second voltage. When the comparator detects that the first voltage is smaller than the second voltage, a counter starts counting. If the value of the counter during said counting exceeds a limiting value, an interruption signal is generated to control an operating mode of an electronic device power by said battery.

  • Patent number: 11742050
    Abstract: A method for detecting a reading error of a datum in memory. A binary word which is representative of the datum and an error correcting or detecting code is read by: reading a first part of the binary word stored at a first address in a first memory circuit; and reading a second part of the binary word stored at a second address in a second memory circuit. The first and second parts read from the first and second memory circuits, respectively, are concatenated to form a read binary word. The datum is then obtained by removing the error correcting or detecting code from the read binary word. A new error correcting or detecting code is calculated from the obtained datum and compared to the removed error correcting or detecting code to detect error in the obtained datum.

  • Publication number: 20230260574
    Abstract: Memory devices such as phase change memory (PCM) devices utilizing Ovonic Threshold Switching (OTS) selectors may be used to fill the gap between dynamic random-access memory (DRAM) and mass storage and may be incorporated in high-end microcontrollers. Since the programming efficiency and reading phase efficiency of such devices is directly linked to the leakage current of the OTS selector as well as sneak-path management, a sense amplifier disclosed herein generates an auto-reference that takes into account the leakage currents of unselected cells and includes a regulation loop to compensate for voltage drop due to read current sensing. This auto-referenced sense amplifier, built utilizing the principle of charge-sharing, may be designed on a 28 nm fully depleted silicon-on-insulator (FDSOI) technology, provides robust performance for a wide range of sneak-path currents and consequently for a large range of memory array sizes, and is therefore suitable for use in embedded memory in high-end microcontroller.

  • Publication number: 20230260835
    Abstract: A method of manufacturing a contact on a semiconductor region includes a step of forming a stack of layers on lateral walls and at a bottom of an orifice (aligned with the semiconductor region) crossing a dielectric region along a longitudinal direction. The step of forming step is carried out from a first surface of the dielectric region and includes forming a polysilicon layer and a layer of a first metal in contact with the polysilicon layer. The first metal is preferably a metal selected from the group of transition metals and is well suited to forming with the polysilicon layer a metal silicide. The method further includes a step of performing thermal anneal causing a reaction between the first metal and the polysilicon layer to produce a layer of metal silicide. At least a portion of that layer of metal silicide extends in the longitudinal direction of the orifice.

  • Patent number: 11721647
    Abstract: A semiconductor wafer includes first zones containing integrated circuits, each first zone including a substrate and a sealing ring at a periphery of the substrate. The first zones are separated from each other by second zones defining cutting lines or paths. The integrated circuit includes an electrically conductive fuse that extends between a first location inside the integrated circuit and a second location situated outside the integrated circuit beyond one of the cutting lines. This electrically conductive fuse includes a portion that passes through the sealing ring and another portion that straddles the adjacent cutting line. The portion of the fuse that passes through is electrically isolated from the sealing ring and from the substrate. The straddling portion is configured to be sliced, when cutting the wafer along the cutting line, so as to cause the fuse to change from an electrical on state to an electrical off state.
