    Abstract: A system-on-chip includes a processor, a memory and a memory interface coupled to the processor and to the memory. The processor, in operation, generates memory access requests. The memory includes one or more physical banks divided into a succession of sectors, each sector having a size equal to a smallest erasable size of the memory. The memory interface, in operation, responds to receiving memory configuration information by storing logical memory bank configuration information in the one or more configuration registers, the logical memory bank configuration information assigning each sector of the one or more physical banks of the memory to a respective logical memory bank of one or more logical memory banks. The memory interface, in operation, controls access to the memory by the processor based on the logical memory bank configuration information stored in the one or more configuration registers.

  • Publication number: 20230168089
    Abstract: A microelectromechanical gyroscope device has: a detection structure, provided with a mobile mass; and an integrated electronic circuit, coupled to the detection structure and which provides a bias signal to the detection structure to cause its oscillation at a resonance frequency and acquires a detection signal from the detection structure indicative of a detected angular velocity. When the gyroscope device is powered, the integrated electronic circuit implements a start-up phase, following a previous power-down, wherein the mobile mass is biased to have an increase in the oscillation up to a target oscillation amplitude, followed by a maintenance phase at the target oscillation amplitude. The integrated electronic circuit is provided with a time counter stage for measuring a duration of a time interval from the previous power-down and adjusts the bias of the mobile mass during the start-up phase as a function of the measured duration of the time interval.

  • Patent number: 11665915
    Abstract: According to principles as discussed herein, an EEPROM cell is provided and then, after testing the code, using the exact same architecture, transistors, memory cells, and layout, the EEPROM cell is converted to a read-only memory (“ROM”) cell. This conversion is done on the very same integrated circuit die using the same layout, design, and timing with only a single change in an upper level mask in the memory array. In one embodiment, the mask change is the via mask connecting metal 1 to poly. This allows the flexibility to store the programming code as non-volatile memory code, and then after it has been tested, at time selected by the customer, some or all of that code from a code that can be written to a read-only code that is stored in a ROM cell that is composed the same transistors and having the same layout.

  • Publication number: 20230160024
    Abstract: A substrate has a plurality of microdots positioned thereon. Each microdot contains one or more primers for gene amplification for a particular target gene. The microdots are placed on the substrate and the substrate is positioned in a housing. The housing has a sample fluid to be tested introduced therein covering the microdot array. While the sample fluid is overlying the substrate, the amplification of the target gene is carried out if it is present within the sample. If the target gene that matches the primers is not present, then amplification will not take place. The fluid also contains fluorophores which will be fixed into the gene as it increases in size as it clearly detects if gene amplification has occurred by detecting the amount of light detected for a particular microdot. In a preferred embodiment, the sample fluid is placed on top of a sealing layer that is less dense then water, such as wax or mineral oil.
