In modern computers, by combining the speed of traditional cache technology, the density of traditional main memory technology, and the non-volatility of flash memory, a new class of emerging byte-addressable nonvolatile memories (NVMs) have great potential to be used as the universal memories of the future. Such memory types include technologies such as phase-change memory, spin-transfer-torque magnetoresistive memory, and resistive memory. As these emerging memory technologies mature, it is important for computer architects to understand their pros and cons in a comprehensive manner in order to improve the performance, power, and reliability of future computer systems incorporating these systems which will be used in various application domains. Yet, most of previous research on NVM architecture is focused only on the performance, power, and density benefits and how to overcome challenges, such as write overhead and wearout issues. The non-volatility characteristic of NVM technologies is not fully explored. Therefore, this project examines how to exploit the non-volatility characteristic that distinguishes the emerging NVM technologies from traditional memory technologies, and investigate new memory architecture design with novel applications.The goal of this project is to advance the memory architecture design of various types of computer systems with a full exploration of the non-volatility characteristic of NVM technologies across architecture, system, and application levels. To this end, the project explores the design space of various types of computer systems, ranging from severs to embedded systems. In particular, the project identifies and addresses design issues in nonvolatile cache architecture, re-architects main memory structure to leverage the non-volatility characteristic to improve system performance and energy consumption, supports persistent memory systems in various use cases with emerging NVM technologies, and studies near-data-computing techniques applied for these NVM technologies. The successful outcome of this research is expected to provide the design guidelines for enabling both large capacity and fast-bandwidth nonvolatile memory/storage, which are beyond the present state-of-the-art. Consequently, the research will spawn new applications involving the computation on the exascale of data, e.g., data mining, machine learning, visual or auditory sensory data recognition, bio-informatics, etc.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在现代计算机中，结合了传统缓存技术的速度、传统主存技术的密度和闪存的非易失性，一类新兴的字节可寻址非易失性存储器(NVM)具有作为未来通用存储器的巨大潜力。这种存储器类型包括诸如相变存储器、自旋转移扭矩磁阻存储器和阻性存储器等技术。随着这些新兴的存储技术的成熟，对于计算机架构师来说，全面地了解它们的优缺点是重要的，以便提高包含这些系统的未来计算机系统的性能、功率和可靠性，这些系统将用于各种应用领域。然而，以前对NVM体系结构的大多数研究只集中在性能、功率和密度方面的优势，以及如何克服挑战，如写入开销和磨损问题。NVM技术的非易失性特征还没有得到充分的探索。因此，本项目研究如何利用新兴NVM技术区别于传统存储技术的非易失性特征，并研究具有新应用的新存储器体系结构设计。本项目的目标是在充分挖掘NVM技术跨体系结构、系统和应用级别的非易失性特征的基础上，推进各种类型计算机系统的存储体系结构设计。为此，该项目探索了从服务器到嵌入式系统的各种类型的计算机系统的设计空间。特别是，该项目确定并解决了非易失性高速缓存体系结构中的设计问题，重新设计了主存储器结构以利用非易失性特性来提高系统性能和能源消耗，利用新兴的NVM技术支持各种使用案例中的持久性存储器系统，并研究应用于这些NVM技术的近数据计算技术。这项研究的成功结果有望为实现大容量和快速带宽的非易失性存储器/存储提供设计指南，这超出了当前最先进的水平。因此，这项研究将产生涉及百亿级数据计算的新应用，例如数据挖掘、机器学习、视觉或听觉数据识别、生物信息学等。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
