Abstract
An imaging sensor having a pixel array with a separate analog-to-digital conversion (ADC) circuit coupled on an input side to each column line and on an output side to a separate M-bit wide digital memory circuit and a column data readout circuit comprising N M-bit data shifters. Each M-bit data shifter has an M-bit wide output, and single pole double throw (SPDT) switches whose common terminals provide inputs to the M-bit data shifters, wherein a first switch state of the SPDT switches connects the input of their associated M-bit data shifters to their associated M-bit wide digital memory circuits and wherein a second switch state of the SPDT switches connects the input of their associated M-bit data shifters to an M-bit wide output bus from an adjacent M-bit data shifter.
