Near-Sensor Computing In article number 2302658, Jianshi Tang and co-workers demonstrate a prototype M3D-SAIL chip for energy-efficient near-sensor computing by monolithic three-dimensional integration of an IGZO-FET based photosensor array, an analog RRAM-based computing-in-memory array, and Si CMOS logic circuits. A video keyframe-extraction task is implemented, achieving a high classification accuracy of 96.7% and 31.5× lower energy consumption and 1.91× faster computing speed compared to its 2D counterpart.
