Abstract: A phase-change memory cell is formed by a heater, a crystalline layer disposed above the heater, and an insulating region surrounding sidewalls of the crystalline layer. The phase-change memory cell supports programming with a least three distinct data levels based on a selective amorphization of the crystalline layer.

Abstract: A device includes serial cyclic redundancy check (CRC) processing circuitry and parallel CRC processing circuitry. The serial CRS processing circuitry, in operation, generates a set of intermediate CRC bits based on a first set of seed bits and input data. The parallel CRC processing circuitry is coupled to the serial CRC processing circuitry, and, in operation, generates, using the set of intermediate CRC bits as a set of parallel seed bits and using null input bits, a set of output CRC bits corresponding to the input data.

Abstract: A micro-heater element for a MEMS sensor device, envisages, in a single conductive layer: an outer ring, defining inside it a window; a heat-diffusion structure, arranged within the window, separated from the outer ring by a first separation gap; and connection elements, arranged between the heat-diffusion structure and the outer ring, and designed to connect the heat-diffusion structure to the outer ring. The outer ring is designed to dissipate energy upon passage of an electric current, and the heat-diffusion structure is designed to distribute, within the micro-heater element, the heat that is transferred by the outer ring through the connection elements.

Abstract: An electronic device comprising: a semiconductor body of silicon carbide, SiC, having a first and a second face, opposite to one another along a first direction, which presents positive-charge carriers at said first face that form a positive interface charge; a first conduction terminal, which extends at the first face of the semiconductor body; a second conduction terminal, which extends on the second face of the semiconductor body; a channel region in the semiconductor body, configured to house, in use, a flow of electrons between the first conduction terminal and the second conduction terminal; and a trapping layer, of insulating material, which extends in electrical contact with the semiconductor body at said channel region and is designed so as to present electron-trapping states that generate a negative charge such as to balance, at least in part, said positive interface charge.

Abstract: A MEMS actuator includes a monolithic body of semiconductor material, with a supporting portion of semiconductor material, orientable with respect to a first and second rotation axes, transverse to each other. A first frame of semiconductor material is coupled to the supporting portion through first deformable elements configured to control a rotation of the supporting portion about the first rotation axis. A second frame of semiconductor material is coupled to the first frame by second deformable elements, which are coupled between the first and the second frames and configured to control a rotation of the supporting portion about the second rotation axis. The first and second deformable elements carry respective piezoelectric actuation elements.

Abstract: An integrated circuit includes a die that includes a circuit configured to generate a PWM signal in response to a first clock signal, and a first set of pads configured to provide amplified PWM signals to external filters. An amplifier stage is configured to provide the amplified PWM signals. The die includes two pads configured to be coupled to an external inductor, and a second set of pads configured to provide regulated voltages. An electronic converter circuit is configured to generate the regulated voltages to supply the amplifier stage. The electronic converter circuit includes a control circuit configured to drive electronic switches in response to a second clock signal to regulate the regulated voltages to a respective target value. The die includes a control block to synchronize the switching activity of the electronic switches with the switching activity of the amplifier stage.

Abstract: A circuit includes a capacitance coupled between a high voltage node and ground, a laser diode having an anode coupled to the high voltage node and a cathode coupled to an output node, and a current source coupled between the output node and ground. The current source turns on based on assertion of a trigger signal and sinks current from the capacitance to ground to thereby cause the laser diode to lase, and turns off based on deassertion of the trigger signal. A clamping circuit is coupled between the output node and the high voltage node, and clamps voltage at the output node occurring when the current source switches off.

Abstract: A light-emitting device may include a semiconductor body having a first conductivity type, with a front side and a back side. The light-emitting device may also include a porous-silicon region which extends in the semiconductor body at the front side, and a cathode region in direct lateral contact with the porous-silicon region. The light-emitting device may further include a barrier region of electrically insulating material, which extends in direct contact with the cathode region at the bottom side of the cathode region so that, in use, an electric current flows in the semiconductor body through lateral portions of the cathode region.

Abstract: In some embodiments, a processing system includes at least one hardware block configured to change operation as a function of configuration data, a non-volatile memory including the configuration data for the at least one hardware block, and a configuration module configured to read the configuration data from the non-volatile memory and provide the configuration data read from the non-volatile memory to the at least one hardware block. The configuration module is configured to: receive mode configuration data; read the configuration data from the non-volatile memory; test whether the configuration data contain errors by verifying whether the configuration data are corrupted and/or invalid; and activate a normal operation mode or an error operation mode based on whether the configuration data contain or do not contain errors.
