Emerging Non-Volatile Memories for Computation-in-Memory

This paper first introduces the principles of different emerging non-volatile memory (NVM) devices. The device structures, working mechanisms, as well as typical performance of these devices are discussed. The technologies for enhancing data storage density, such as three-dimension integration, multi-level cell, are also discussed. Then different approaches of computation-in-memory (CIM) based on emerging NVM will be presented, specially focus on vector-matrix-multiplication. Later, the paper will summary the performance requirements and key challenges on the device level to realize the CIM. Finally, this paper will provide some possible research directions in the future development on emerging NVM for CIM applications.
