  2. Nonvolatile BIOS memory - Wikipedia

    en.wikipedia.org/wiki/Nonvolatile_BIOS_memory

    Nonvolatile BIOS memory refers to a small memory on PC motherboards that is used to store BIOS settings. It is traditionally called CMOS RAM because it uses a volatile, low-power complementary metal–oxide–semiconductor (CMOS) SRAM (such as the Motorola MC146818 [1] or similar) powered by a small battery when system and standby power is off.

    A micrograph of the corner of the photosensor array of a webcam digital camera Image sensor (upper left) on the motherboard of a Nikon Coolpix L2 6 MP. The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.

    2009 Nobel Prize in Physics laureates George E. Smith and Willard Boyle, 2009, photographed on a Nikon D80, which uses a CCD sensor. The basis for the CCD is the metal–oxide–semiconductor (MOS) structure, [2] with MOS capacitors being the basic building blocks of a CCD, [1] [3] and a depleted MOS structure used as the photodetector in early CCD devices.

  6. Active-pixel sensor - Wikipedia

    en.wikipedia.org/wiki/Active-pixel_sensor

    The active circuitry in CMOS pixels takes some area on the surface which is not light-sensitive, reducing the photon-detection efficiency of the device (microlenses and back-illuminated sensors can mitigate this problem). But the frame-transfer CCD also has about half the non-sensitive area for the frame store nodes, so the relative advantages ...
