  • Patent number: 11933847
    Abstract: The invention relates to an apparatus and a system for debugging a solid-state disk (SSD) device. The apparatus includes a Joint Test Action Group (JTAG) add-on board; and a Raspberry Pi. The Raspberry Pi includes a General-Purpose Input/Output (GPIO) interface (I/F), coupled to the JTAG add-on board; and a processing unit, coupled to the GPIO I/F. The processing unit is arranged operably to: simulate to issue a plurality of JTAG command through the GPIO I/F to the SSD device for dumping data generated by the SSD device during operation from the SSD device.

  • Patent number: 10739682
    Abstract: Various embodiments of the present application are directed towards an edge-exposure tool with a light emitting diode (LED), as well as a method for edge exposure using a LED. In some embodiments, the edge-exposure tool comprises a process chamber, a workpiece table, a LED, and a controller. The workpiece table is in the process chamber and is configured to support a workpiece covered by a photosensitive layer. The LED is in the process chamber and is configured to emit radiation towards the workpiece. A controller is configured to control the LED to expose an edge portion of the photosensitive layer, but not a center portion of the photosensitive layer, to the radiation emitted by the LED. The edge portion of the photosensitive layer extends along an edge of the workpiece in a closed path to enclose the center portion of the photosensitive layer.
