The first type semiconductor layer is formed on a semiconductor substrate and includes a plurality of pixels which receive external light and convert optical charges into an electrical signal. The second type semiconductor layer is supplied with a drain voltage to have a potential different from that of the first semiconductor layer, and the first type well controls a power source voltage (VDD) using the drain voltage.
Abstract:
A method of inter-layer search of a multi-layer disk, the method including determining whether a search is required of a layer other than a currently accessed layer; searching the currently accessed layer for a position corresponding to a target address on the layer not currently accessed; and moving access to the layer not currently accessed according to the position corresponding to the target address.
Abstract:
An apparatus and method of performing a stable pause motion of an optical pickup over an optical disk which has both an occupied area and an unoccupied area. Start addresses and end addresses of occupied areas on the optical disk are stored. When the optical pickup is over an unoccupied area, a pause-on command to maintain a current location of the optical pickup is issued. The optical pickup is moved to an end address of an occupied area being the closest to an address where the optical pickup is placed at the moment when the pause-on command is issued. Accordingly, the optical pickup stably pauses over the optical disk having both an occupied area and an unoccupied area.
Abstract:
For driving an image sensor having a pixel with a transfer gate formed between a photo-detector and a floating diffusion region, a noise-reducing voltage is applied on the transfer gate during a first period of an integration mode. A blooming current voltage is applied on the transfer gate during a second period of the integration mode. A read voltage is applied on the transfer gate during a read mode after the integration mode. The read voltage has a higher magnitude than the blooming current voltage. With application of the noise-reducing voltage, noise is reduced and a dynamic range is extended for the image sensor.
Abstract:
A method and apparatus for detecting a free page of a memory device, and a method and apparatus for decoding an error correction code by using the method and apparatus for detecting a free page are provided. Free page data read from the memory is converted into a converted codeword for inclusion as an element of an error correction code field. The converted codeword is compared to an initially set target codeword to detect an amount of non-identical bits. A page read from the memory is determined to be a free page when the amount of non-identical bits is equal to or less than an initially set threshold value.
