CCD, Semiconductor device in which the individual semiconductor components are connected so that the electrical charge at the output of one device provides the input to the next device. Because they can store electrical charges, CCDs can be used as memory devices, but they are slower than RAMs. CCDs are sensitive to light, and are therefore used as the light-detecting components in video and digital cameras and in optical scanners.
