Trend of Emerging Non-Volatile Memory for AI Processor

Processing unit and memory are key components for artificial intelligent (AI) processor, which are developed by the CMOS technology and static random access memory (SRAM), respectively. As technology scaling down to sub-30 nm, the leakage current has become a critical issue to AI processor. Recently, the emerging non-volatile memory is mature gradually, such as Magnetic RAM (MRAM) and Resistive RAM (RRAM), which can be used to develop AI processor to alternate both processing unit and memory. In this work, we provide a survey on the recent tape-out work on MRAM and RRAM. We discuss the trend of MRAM and RRAM as buffer/Cache, and computingin Memory architecture. Based on the recent developments, we predict both MRAM and RRAM can be a AI product soon.
