ABSTRACT:
A CMOS image pixel array formed on a chip is used for storing programmed information within the pixel array. Manufacturing lot and other data is written to the array during manufacturing and testing by applying a laser to pixels to render the photodiode defective. The programmed data is read from the pixel array using existing circuitry.
