Abstract
A complementary metal-oxide semiconductor (CMOS) image sensor (CIS) with a simplified stacked structure and improved operation characteristics includes an upper chip, in which a plurality of pixels are arranged in a two-dimensional array structure, and a lower chip below the upper chip including a logic region having logic circuits and a memory region having embedded therein magnetic random access memory (MRAM) used as image buffer memory for storing image data processed by the logic region.
