Selector-only memory 기반 차세대 메모리 기술의 이해와 전망

초록

With the rapid advancement of high-performance computing systems, the demand for memory technologies that offer both simplified architectures and high scalability continues to grow. Selector-Only Memory (SOM) has emerged as a promising innovation, enabling both memory storage and effective suppression of leakage currents using only selector devices. This paper presents a comprehensive review of SOM, emphasizing its structure, operating principles, and recent research on composition-dependent property variations as well as switching mechanisms in chalcogenide-based materials. Furthermore, strategies for materials and process optimization aimed at achieving high integration density and practical implementation are discussed, alongside the key technical challenges that remain. This work aims to enhance the understanding of SOM’s potential as a next-generation memory technology and to provide guidance for future research directions.
