  • Patent number: 11289134
    Abstract: Devices, systems, and methods for reducing sensing delays for a non-volatile memory reading circuit may include operations for pre-charging a plurality of bit lines coupling a memory array having multiple bit cells with a sensing amplifier. Upon receiving a read request identifying a given bit cell in the memory array, the addressed bit line is decoupled from a bias voltage. The addressed bit line corresponds to the given bit cell and is selected from the plurality of bit lines. With the decoupling from the bias voltage, the addressed bit lines are coupled to the sensing amplifier. After a sensing circuit delay, data stored in the given bit cell is provided to the sensing amplifier via the addressed bit lines coupled to the sensing amplifier. The data stored in the given bit cell may then be interpreted by the sensing amplifier and a corresponding data output signal is generated.

    Abstract: A semiconductor device may include a plurality of single-photon avalanche diodes (SPADs). The semiconductor device may include sensing single-photon avalanche diodes that are sensitive to incident light and dark single-photon avalanche diodes that are shielded from incident light. The dark single-photon avalanche diodes may be used to measure one or more parameters for the semiconductor device such as breakdown voltage, dark count rate, and quench resistance. Processing circuitry may optimize a bias voltage for the semiconductor device based on information regarding one or more sensor parameters obtained using the dark single-photon avalanche diodes.

  • Publication number: 20210223398
    Abstract: A light detection and ranging (LIDAR) imaging system may include a semiconductor device based on single-photon avalanche diodes (SPADs). The LIDAR imaging system may also include a light source configured to emit light such that the semiconductor device is exposed to both ambient light and a reflected version of the laser light. Ambient light level detection circuitry may be included to determine a brightness of the ambient light based on an output signal from the semiconductor device. The ambient light level detection circuitry may include a plurality of comparators that receive different reference signals and are coupled to respective counters. The results from the counters may be used to determine the brightness of the ambient light in the scene. The determined brightness may then be used to discriminate between the ambient light and the reflected version of the light.

  • Publication number: 20210223372
    Abstract: An imaging system may include a silicon photomultiplier with single-photon avalanche diodes (SPADs). The imaging system may be a LIDAR imaging system with LIDAR processing circuitry. To reduce memory requirements in the LIDAR processing circuitry, a dynamic resolution storage scheme may be used. The LIDAR processing circuitry may include autonomous dynamic resolution circuitry that receives input from a time-to-digital converter (TDC). The autonomous dynamic resolution circuitry may include a plurality of memory banks having different resolutions. Based on the magnitude of the input from the TDC, an appropriate memory bank may be selected. In parallel, an address encoder may select a memory bin based on the input from the TDC.
