US Patent 9911782 Semiconductor device and method for driving the same

The semiconductor device includes a plurality of pixels arranged in rows and columns, and first transistors fewer than the number of the plurality of pixels. The plurality of pixels each includes a photodiode and an amplifier circuit. The amplifier circuit holds the accumulated charge and includes at least a second transistor electrically connected to a cathode of the photodiode. The cathode of the photodiode in the pixel in an n-th row and the cathode of the photodiode in the pixel in an (n+1)-th row are electrically connected to the first transistor. The number n is a natural number. The pixel in the n-th row and the pixel in the (n+1)-th row are in an identical column.
