Monolithic 3D Integration of Analog RRAM‐Based Computing‐in‐Memory and Sensor for Energy‐Efficient Near‐Sensor Computing (Adv. Mater. 22/2024)

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.
