Abstract: A system includes a processor and a memory. The processor locates a first memory chip that is faulty in a memory. After the first memory chip is isolated or replaced, the processor may reset the first memory chip when other memory chips in the memory are maintained to work normally. When a fault occurs in a memory chip in the memory, after the first memory chip that is faulty is isolated or replaced, the processor may independently reset the first memory chip without affecting the other memory chips in the memory. Resetting the first memory chip enables the first memory chip to restore to normal. A memory chip that can be normally used is used as a redundant memory chip or may continue to be used.

Abstract: The present disclosure relates to laser treatment of an optical fiber to secure the optical fiber within a ferrule bore.

Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk, the display may include active and/or passive leakage-mitigating structures. The passive leakage-mitigating structures may have an undercut that causes discontinuities in the overlying OLED layers. Active leakage-mitigating structures may include a conductive layer (e.g., a conductive ring) that drains leakage current to ground. Alternatively, the active leakage-mitigating structures may include a gate electrode modulator with a variable voltage that stops the current flow laterally.
