One or more dummy pixels of an image sensor device IC are modified to include programming circuitry that enables them to be used as non-volatile memory. Dummy pixels are non-imaging pixels that already exist in image sensor ICs and are addressable using the same circuitry that is used to address the imaging array of the IC. Therefore, there are no additional processing steps and no additional cost associated with implementing the dummy pixels or circuitry for addressing the dummy pixels in the IC. One or more of these non-imaging dummy pixels are modified to make the dummy pixels programmable to enable the pixels to store logic 1 bits and logic 0 bits.
