Abstract: This is generally directed to systems and methods for providing shiftable column circuitry for a pixel array of an imaging system. Columns of a pixel array can be switchably coupled (e.g., through multiplexers) to their default column circuitry as well as coupled to one or more instances of a neighboring column's column circuitry. In response to an instance of default column circuitry being identified as defective, its corresponding column may “shift” and choose to couple to the neighboring column circuitry. Similarly, all following columns may also shift and couple to a neighboring column circuitry. In some embodiments, the defective column circuitry can be identified during wafer testing and identifying information (e.g., an address) of the defective column circuitry stored in memory. The identifying information may then be accessed from memory and, during an image signal readout phase, used to suitably shift the columns to avoid the defective column circuitry.
