A collaborative research team, hailing from the Southern University of Science and Technology (SUSTech) and Xi'an Jiaotong University, has successfully developed the world's inaugural precision-lossless, fully parallel digital non-volatile in-memory computing chip. Leveraging cutting-edge 40-nanometer CMOS technology alongside STT-MRAM, this innovative chip effectively addresses the longstanding challenges of computational accuracy and scalability that have plagued traditional analog in-memory computing architectures. This breakthrough is achieved through the implementation of a novel 'in-cell multiplication and digitization' design, which enables the chip to perform high-efficiency, lossless-precision matrix computations. This advancement paves the way for AI chips to transcend the 'memory wall' limitation, offering a promising new avenue for future technological developments. The groundbreaking research findings have been duly published in the esteemed journal Nature Electronics.
