  • Patent number: 8598639
    Abstract: A silicon photodiode with symmetry layout and deep well bias in CMOS technology is provided. The silicon photodiode includes a substrate, a deep well, and a PN diode structure. The deep well is disposed on the substrate, where an extra bias is applied to the deep well. The region surrounded by the deep well forms the main body of the silicon photodiode. The PN diode structure is located in the region surrounded by the deep well, where the silicon photodiode has a symmetry layout. The deep well is adopted when fabricating the silicon photodiode, and the extra bias is applied to the deep well to eliminate the interference and effect of the substrate absorbing light, and further greatly improve speed and bandwidth. Furthermore, the silicon photodiode has a symmetry layout, so that uniform electric field distribution is achieved, and the interference of the substrate noise is also reduced.

  • Patent number: 7516316
    Abstract: A method for loading configuration data onto a non-volatile memory and the device using the same is provided. A non-volatile memory block is preloaded with a certain compatible memory configuration data in advance when the memory device is being manufactured. The memory configuration data comprises plural parameters corresponding to the non-volatile memory. When readying the memory device, the preloaded configuration data is loaded onto a random-access memory thereof so as to save the space in a read-only memory used for storing the memory's identification and its specification. Additionally, means for loading the configuration data from the preload zone onto the random-access memory is introduced to update the firmware.
