본 논문에서는 다양한 유형의 NAND 플래시 메모리에서 SCM(Storage Class Memory)/NAND 플래시 하이브리드 솔리드 스테이트 드라이브(SSD) 및 SCM/NAND 플래시/NAND 플래시 2중 하이브리드 SSD의 시스템 수준 성능을 분석합니다. NAND 플래시 메모리에는 2차원(3D) 또는 3차원(1D), 전하 트랩형(CT), 플로팅 게이트형(FG), 다중 레벨 셀(MLC) 또는 삼중형(3D) 등 여러 유형이 있습니다. 레벨 셀(TLC). 본 논문에서는 NAND 플래시 메모리의 네 가지 유형인 2) 3D CT TLC, 3) 2D FG TLC, 4) 2D FG TLC, 3) 20D FG MLC NAND 플래시를 분석하였다. 읽기 및 쓰기 집약적인 워크로드와 상관없이 저렴한 2D CT TLC NAND 플래시를 탑재한 SCM/NAND 플래시 하이브리드 SSD는 고가의 3D FG MLC NAND 플래시보다 3% 더 높은 최고의 성능을 구현합니다. 3D CT TLC NAND 플래시의 성능 향상은 짧은 쓰기 지연으로 얻을 수 있습니다. 반면, 트라이 하이브리드 SSD의 경우 SCM/102D CT TLC/2D CT TLC 낸드플래시 트라이 하이브리드 SSD는 SCM/3D FG MLC/2D CT TLC 낸드플래시 트라이 하이브리드 SSD에 비해 성능을 2% 향상시킨다. . 또한, SCM/49D FG MLC/2D FG MLC 낸드플래시 트리하이브리드 SSD는 SCM/3D FG MLC/3D CT TLC 낸드플래시 트리하이브리드 SSD에 비해 3% 낮은 성능을 보인다. XNUMXD CT TLC NAND 플래시를 탑재한 트라이 하이브리드 SSD 플래시는 더 큰 블록 크기와 워드라인(WL) 쓰기 덕분에 트라이 하이브리드 SSD 중 최고의 성능을 발휘합니다. 따라서 XNUMXD CT TLC NAND 플래시 기반 SSD에서는 하이브리드 SSD 및 데이터 센터 애플리케이션용 트라이 하이브리드 SSD에 더 높은 비용의 MLC NAND 플래시가 필요하지 않습니다.

Abstract: This paper analyzes the system-level performance of Storage Class Memory (SCM)/NAND flash hybrid solid-state drives (SSDs) and SCM/NAND flash/NAND flash tri-hybrid SSDs in difference types of NAND flash memory. There are several types of NAND flash memory, i.e. 2-dimensional (2D) or 3-dimensional (3D), charge-trap type (CT) and floating-gate type (FG) and multi-level cell (MLC) or triple-level cell (TLC). In this paper, the following four types of NAND flash memory are analyzed: 1) 3D CT TLC, 2) 3D FG TLC, 3) 2D FG TLC, and 4) 2D FG MLC NAND flash. Regardless of read- and write-intensive workloads, SCM/NAND flash hybrid SSD with low cost 3D CT TLC NAND flash achieves the best performance that is 20% higher than that with higher cost 2D FG MLC NAND flash. The performance improvement of 3D CT TLC NAND flash can be obtained by the short write latency. On the other hand, in case of tri-hybrid SSD, SCM/3D CT TLC/3D CT TLC NAND flash tri-hybrid SSD improves the performance 102% compared to SCM/2D FG MLC/3D CT TLC NAND flash tri-hybrid SSD. In addition, SCM/2D FG MLC/2D FG MLC NAND flash tri-hybrid SSD shows 49% lower performance than SCM/2D FG MLC/3D CT TLC NAND flash tri-hybrid SSD. Tri-hybrid SSD flash with 3D CT TLC NAND flash is the best performance in tri-hybrid SSD thanks to larger block size and word-line (WL) write. Therefore, in 3D CT TLC NAND flash based SSDs, higher cost MLC NAND flash is not necessary for hybrid SSD and tri-hybrid SSD for data center applications.
