Modern computing systems require manipulation of persistentdata. However, the mechanisms to access persistent data are separatedfrom the mechanisms to manipulate such data in a traditional two-levelstorage model: persistent data is stored in non-volatile storage, suchas hard disks or solid-state disks, whereas it is manipulated involatile memory, such as DRAM. Unfortunately, this decoupled model ofsystem design leads to large amounts of inefficiency in terms of bothperformance and energy.This research undertakes a rethinking of the memory and storagesystems in the presence of new and emerging non-volatile memorytechnologies such as phase-change memory , spin-transfer torque RAM,and memristors. These technologies promise large capacities at lowlatency, making them prime candidates for the design of a single-levelcoordinated memory and storage system where the manipulation andstorage of all data are unified. Yet, there are significantapplication-level and system-level efficiency and correctnesschallenges in devising such a single-level store with emergingtechnologies. The central goal of this project is to develophardware/software cooperative techniques to enable high-performanceand energy-efficient single-level stores in computer systems targetinga wide range of applications in cloud computing, client systems, andmobile systems.It is expected that research performed in this project will enable newapplications and much more robust and efficient data storage systems,making our daily lives that increasingly depend on data processingbetter and more productive. Enabling unified memory and storage formodern computing systems can largely reduce wasted work and takeadvantage of emerging low-power technologies, thereby taking a largestep in making computing more energy efficient.

现代计算系统需要对持久数据进行操作。然而，在传统的两级存储模型中，访问持久数据的机制与操作这些数据的机制是分开的：持久数据存储在非易失性存储中，例如硬盘或固态磁盘，而操作持久数据的是非易失性内存，例如DRAM。不幸的是，这种系统设计的解耦模型在性能和能量方面都导致了大量的低效率。本研究在新兴的非易失性存储器技术如相变存储器、自旋转移扭矩RAM和忆阻器的存在下，对存储器和存储系统进行了重新思考。这些技术保证了在低延迟下的大容量，使它们成为单级协调内存和存储系统设计的主要候选者，其中所有数据的操作和存储是统一的。然而，在使用新兴技术设计这样的单级存储时，存在重大的应用级和系统级效率和正确性挑战。该项目的中心目标是开发硬件/软件协作技术，以实现针对云计算、客户端系统和移动系统的广泛应用的计算机系统中的高性能和节能单级存储。预计在这个项目中进行的研究将使新的应用和更强大、更高效的数据存储系统成为可能，使我们的日常生活越来越依赖于数据处理，变得更好、更高效。为现代计算系统启用统一的内存和存储可以在很大程度上减少浪费的工作，并利用新兴的低功耗技术，从而在使计算更节能方面迈出了一大步。
