Abstract
An image sensor in which a pixel array and a memory cell array are merged includes a first semiconductor chip including the pixel array and the memory cell array in a same semiconductor chip, and a second semiconductor chip overlapping the first semiconductor chip in a vertical direction. The second semiconductor chip includes a first logic circuit that controls the pixel array, an analog-to-digital converter (ADC) that converts an analog signal output from the pixel array under control of the first logic circuit to a digital signal, and a second logic circuit that stores data that is output from the ADC circuit based on the digital signal to the memory cell array of the first semiconductor chip.
