Abstract: The system and method of memory protection using a tagged architecture. The system of memory protection provides a unique tag for each field, within a structure, thus preventing access beyond the structure. The system compares the unique tag, e.g. color, of each field within the structure to the color of the pointer that is used to access the respective structure field. Freed memory is tagged as uninitialized.

The parasitic photodiode also serves the function of a floating diffusion node in the pixel.
