Abstract
A CMOS image sensor formed on a chip has a ROM disposed on the chip for recording pixel defect locations, chip-by-chip variations such as bias, and other manufacturing production data. Testing results and repair solutions are written to the ROM after production testing. A simple circuit for writing information to the ROM also is provided on the CMOS chip. During operational use of the image sensor, data is read from the on-chip ROM to assist in compensating for manufacturing process variations.
