ABSTRACT:
The image sensor includes a plurality of pixels, arranged in rows and columns to form a pixel array, each pixel having a pixel output. The image sensor includes at least two column bitlines for each pixel column, each column bitline connected to each pixel output in the pixel column and to a common readout amplifier. In one embodiment, the bitlines are not in the same plane and multiple bitlines are positioned one above the other, maximizing pixel efficiency.
