Recently DRAM and PRAM hybrid main memory organization has been studied in order to address the high levels of energy dissipation in DRAM based main memory. It is expected that this new memory architecture will be used soon in mobile computers which use NAND Flash memory based storages. In such computers, legacy operating system functionalities like file system and memory system should be modified in order efficiently to manage heterogeneous memory organization. In this paper, the authors study a new buffer cache scheme which considers DRAM/PRAM hybrid main memory and flash memory based storages.
