FRASH: Hierarchical File System for FRAM and Flash
In this paper, the authors develop novel file system, FRASH, for byte-addressable NVRAM and NAND flash device. Byte addressable NVRAM and NAND flash is typified by the DRAM-like fast access latency and high storage density, respectively. Hierarchical storage architecture which consists of byte-addressable NVRAM and NAND Flash device can bring synergy and can greatly enhance the efficiency of file system in various aspects. Unfortunately, current state of art file system for Flash device is not designed for byte-addressable NVRAM with DRAM-like access latency.
