Computing-in-Memory with SuperFlash® memBrain™ Technology

Abstract

The concept and experimental result of using SuperFlash® based neuromorphic memory to solve the data communication bottlenecks in neural network edge devices are discussed. The implementation of a 2Mb memory array as an analog vector matrix multiplier (VMM) in a 28 nm SuperFlash® eFlash (ESF3-28 nm) process together with design concepts, weight tuning technique, performance factors, and reliability, are also presented in detail.
