Challenges in Design, Data Placement, Migration and Power-Performance Trade-offs in DRAM-NVM-based Hybrid Memory Systems

Rai, S.Talawar, B.2026-02-082023IETE Technical Review (Institution of Electronics and Telecommunication Engineers, India), 2023, Vol.40, 4, p.498 -5202564602https://doi.org/10.1080/02564602.2022.2127945https://idr.nitk.ac.in/handle/123456789/34279DRAM-NVM-based hybrid memory opens up a varied range of power-performance-area operational configurations through page migration between the high-performance DRAM and the reliable NVM. The amalgamation of two technologies requires various modifications for the existing monolithic DRAM-based systems. This paper summarizes the current research work in the areas of data placement and page migration in hybrid memories. The challenges and design solutions from a range of NVMs-PCM, STT-RAM, ReRAM is presented. This paper also identifies several research challenges in these areas.
