“…To ease the memory pressure of smartphones, Zhong et al [2014] implemented NVMSwap, which builds a swap area for smartphone systems with NVM. Specifically, they proposed copy-on-write swap-in (COWS), so that read requests can get data directly from the swap area with zero memory copy.…”

With dramatic growth of data and rapid enhancement of computing powers, data accesses become the bottleneck restricting overall performance of a computer system. Emerging phase-change memory (PCM) is byte-addressable like DRAM, persistent like hard disks and Flash SSD, and about four orders of magnitude faster than hard disks or Flash SSDs for typical file system I/Os. The maturity of PCM from research to production provides a new opportunity for improving the I/O performance of a system. However, PCM also has some weaknesses, for example, long write latency, limited write endurance, and high active energy. Existing processor cache systems, main memory systems, and online storage systems are unable to leverage the advantages of PCM, and/or to mitigate PCM's drawbacks. The reason behind this incompetence is that they are designed and optimized for SRAM, DRAM memory, and hard drives, respectively, instead of PCM memory. There have been some efforts concentrating on rethinking computer architectures and software systems for PCM. This article presents a detailed survey and review of the areas of computer architecture and software systems that are oriented to PCM devices. First, we identify key technical challenges that need to be addressed before this memory technology can be leveraged, in the form of processor cache, main memory, and online storage, to build high-performance computer systems. Second, we examine various designs of computer architectures and software systems that are PCM aware. Finally, we obtain several helpful observations and propose a few suggestions on how to leverage PCM to optimize the performance of a computer system.

The mobile devices such as smartphones and tablets are increasing processor speed and they are desired more energy. We focus on the emerging non volatile memory (NVM), which has gained attention in recent years. A non volatile memory is new memory technology such as SST-MRAM, PCM and ReRAM. Any devices also can be accessed in byte units, high speed nanoseconds access latency and higher write endurance than the flash memory. Thus, it is possible to replace the DRAM of the main memory by the NVM, it is possible to achieve reducing the power consumption. Although potentially possible of large capacity, NVM product of capacity greater than DRAM is currently not appeared now. We should provide a large memory space without performance degradation by in combination with NVM and other memory devices. In this paper, we propose a method to use the DRAM as swap space. The proposed method provides an experimental design of the non volatile main memory system. It enables both of high-performance and energy efficiency.

“…Table II summarizes the application sets used in our experiments. To guarantee the effectiveness of our experimental results, we conduct experiments with the Android UI/Application Exerciser Monkey, a stress test tool in the Android SDK that can generate pseudo-random streams of user events such as clicks, touches and gestures [24]. When applications are specified in Monkey parameters, it would run the random events generated by Monkey.…”

Virtualization offers significant benefits such as better isolation and security for mobile systems. However, the limited amount of memory and virtualization's memory-demanding nature makes it challenging to virtualize mobile systems efficiently. In this paper, we utilize morphable resistive memories to design a high-performance mobile system with extensible memory space. With morphable resistive memory, we convert the memory cell state between multi-level and single-level to achieve a balance between performance and memory space. Our evaluation based on the Samsung Exynos 5250 SoC with real Android applications shows that our system achieve 27% performance improvement compared with the baseline scheme.
