  • Publication number: 20240105118
    Abstract: A device may include an electronic display to display an image frame based on image data. The electronic display may include an illuminator that generates light, multiple light regulators that control emission of the light pixel locations on the electronic display based on bitplane data, and driving circuitry that applies an operating electrical stimulus to the illuminator during an emission period of the image frame and a reference electrical stimulus to the illuminator during an off period of the image frame. While the reference electrical stimulus is applied the bitplane data may be indicative of off bitplane. Additionally, the electronic display may include measurement circuitry that measures a response characteristic of the illuminator in response to the reference electrical stimulus and generates temperature data indicative of the temperature of the illuminator based on the response characteristic.

  • Patent number: 10026492
    Abstract: Systems and methods for improving the reliability of data stored in memory cells are described. To mitigate the effects of trapped electrons after one or more programming pulses have been applied to memory cells, a delay between the one or more programming pulses and subsequent program verify pulses may be set based on a chip temperature, the number of the one or more programming pulses that were applied to the memory cells, and/or the programming voltage that was applied to the memory cells during the one or more programming pulses. To mitigate the effects of residual electrons after one or more program verify pulses have been applied to memory cells, a delay between the one or more program verify pulses and subsequent programming pulses may be set based on a chip temperature and/or the programming voltage to be applied to the memory cells during the subsequent programming pulses.

  • Patent number: 9548124
    Abstract: A memory device includes memory cells arranged in word lines. Due to variations in the fabrication process, with width and spacing between word lines can vary, resulting in widened threshold voltage distributions. In one approach, a programming parameter is optimized for each word line based on a measurement of the threshold voltage distributions in an initial programming operation. An adjustment to the programming parameter of a word line can be based, e.g., on measurements from adjacent word lines, and a position of the word line in a set of word lines. The programming parameter can include a programming mode such as a number of programming passes. Moreover, the programming parameters from one set of word lines can be used for another set of word lines having a similar physical layout due to the variations in the fabrication process.

  • Patent number: 9406824
    Abstract: The present disclosure relates to a nanopillar tunneling photovoltaic (“NPTPV”), and method for fabricating it. The NPTPV device has a regular array of semiconductor pillar cores formed on a substrate having a conductive surface. Layers of high-k material are formed on the cores to provide an efficient tunneling layer for electrons (or holes) generated by incident photons in the cores. Transparent conductive collector layers are formed on the tunneling layer to collect the tunneled carriers. An optimized deposition process, various surface preparations, an interfacial layer between the pillars and the high-k tunnel layer, and optimized pre- and post-deposition annealing reduce the interface trap density and thus reduce recombination prior to tunneling. The absence of a junction also reduces core recombination, resulting in a high short-circuit current. Modifying the collector material and core doping tunes the open-circuit voltage. Such NPTPVs result in large-scale low-cost PVs.

  • Patent number: 9343164
    Abstract: A method and non-volatile storage system are provided in which the voltage applied to the source end of a NAND string depends on the location of the non-volatile storage element that is selected for sensing. This may be done without body-biasing the NAND string. Having the magnitude of the voltage applied to the source end of a NAND string depend on the location of the selected memory cell (without any body biasing) helps to mitigate failures that are dependent on which word line is selected during a sensing operation of one embodiment. Additionally, the magnitude of a read pass voltage may depend on either the source line voltage or the location of the selected memory cell.
