Abstract
Recently, NAND flash memory has been widely adopted as a storage medium in various devices such as mobile phones, MP3 players, and digital cameras. In particular, Solid State Drives (SSDs), which are composed of multiple NAND flash memories, have gradually replaced hard disk drives (HDD). However, SSDs have an inherent weakness stemming from NAND flash memory and its complex architecture. This phenomenon makes it difficult to analyze and optimize the performance of SSD controllers. To overcome this weakness, highly accurate system simulations are needed for exploring architectural parameters to maximize the performance during the design phase. In this paper, we implement a simulator that considers all of the hardware components in SSD to assist in generating quantitatively accurate analysis when an algorithm or controller is realized. This simulator models the detailed characteristics of hardware components such as operation clock frequency and resource conflicts in order to represent SSD in great detail. In the experiments section, we verify the impacts of interface speed, page size, and other configuration parameters by using this cycle accurate simulator. These analysis results can then be used as raw data for optimization.
