在本文中,我们提出了PDRAM,一种新的能源效率的主存储器架构的基础上相变随机存取存储器(PRAM)和DRAM。本文探讨了将PRAM纳入计算系统的主存储器层次结构所面临的挑战,并提出了一种低开销的混合硬件-软件解决方案来管理它。我们的实验结果表明,我们的解决方案是能够实现平均节能30%,在传统的存储器架构可以忽略不计的开销。
In this paper, we propose PDRAM, a novel energy efficient main memory architecture based on phase change random access memory (PRAM) and DRAM. The paper explores the challenges involved in incorporating PRAM into the main memory hierarchy of computing systems, and proposes a low overhead hybrid hardware-software solution for managing it. Our experimental results indicate that our solution is able to achieve average energy savings of 30% at negligible overhead over conventional memory architectures.
