“…Another similar and common trend in hybrid memories is to use fast memory (PM or DRAM) to store frequently accessed data. In this case, the file system needs a strategy of block placement to decide whether data (pages, blocks or files) should be stored in fast and volatile memory or in slower, higher-capacity persistent memory [30], [112], [116], [141]. This strategy must identify critical data and determine whether they are temporary or must be persisted.…”

For decades, computer architectures have treated memory and storage as separate entities. Nowadays, we watch the emergence of new memory technologies that promise to significantly change the landscape of memory systems. Byte-addressable non-volatile memory (NVM) technologies are expected to offer access latency close to that of dynamic random access memory and capacity suited for storage, resulting in storage-class memory. However, they also present some limitations, such as limited endurance and asymmetric read and write latency. Furthermore, adjusting the current hardware and software architectures to embrace these new memories in all their potential is proving to be a challenge in itself. In this paper, recent studies are analyzed to map the state-of-the-art of NVM file systems research. To achieve this goal, over 100 studies related to NVM systems were selected, analyzed, and categorized according to their topics and contributions. From the information extracted from these papers, we derive the main concerns and challenges currently being studied and discussed in the academia and industry, as well as the trends and solutions being proposed to address them.

Rapidly evolving technology, increased internet speed and capacity, and the widespread use of mobile technologies have increased the demands for faster applications and less power consumption of modern electronic systems. In modern electronic systems, RAM is as effective as CPU regarding performance and power consumption. Although DRAM is the most used types of main memory today, it has been insufficient in terms of provide increasing demands. One of the issues to be addressed is to improve DRAM in terms of performance and power consumption. Another study to address this increasing demand is the development of hybrid main memory architectures. Hybrid Main Memory is one of the most recent studies on RAM. In this research, we investigate hybrid main memory systems for a more efficient main memory architecture.
