可靠节能PCM系统的设计方法
Design Methodologies for Reliable and Energy-efficient PCM Systems
摘要：
相变存储器（PCM）是一种可扩展且低延迟的非易失性存储器（NVM）技术，其已被提出用作存储类存储器（SCM），提供类似于DRAM的低访问延迟，并且通常接近或超过SSD的容量。PCM的多层次特性也使其在神经形态系统中的采用，以建立高密度的突触存储。我们调查和描述PCM系统的两个重要瓶颈。首先，写入PCM单元比读取其内容引起显著更高的延迟和能量损失。其次，PCM的高工作电压影响其可靠工作。在这项工作中，我们提出了解决瓶颈的方法，提高性能，可靠性，能源消耗和PCM系统的可持续性。
英文摘要：
Phase-change memory (PCM) is a scalable and low latency non-volatile memory (NVM) technology that has been proposed to serve as storage class memory (SCM), providing low access latency similar to DRAM and often approaching or exceeding the capacity of SSD. The multilevel property of PCM also enables its adoption in neuromorphic systems to build high-density synaptic storage. We investigate and describe two significant bottlenecks of a PCM system. First, writing to PCM cells incurs significantly higher latency and energy penalties than reading its content. Second, high operating voltages of PCM impacts its reliable operations. In this work, we propose methodologies to tackle the bottlenecks, improving performance, reliability, energy consumption, and sustainability for a PCM system.
