Emerging memories (EMs) have been intensively explored for embedded non-volatile memory (eNVM) applications because of their advantages over conventional eNVMs. There has been limited production of microcontrollers with embedded EM (eEMs) but the eEMs market has not taken off yet. The disruptive innovation undertaken by advanced digital CMOS technologies now provides a compelling motivation for a radical change, giving eEMs a great opportunity for success. Phase change memory (PCM) has been proven, in stand-alone memories, to be the most mature among the various kinds of EM. This paper illustrates the enormous potential of PCM in the field of eNVM. The evolution of embedded PCM (ePCM) is reviewed, showing evidence for the effort spent to enlarge the operating temperature range to cover an automotive mission profile. The recently disclosed state-of-the-art 28 nm HK metal gate fully depleted silicon-on insulator ePCM is presented as the demonstration of the ePCM potential to becom...

用于汽车级嵌入式NVM应用的相变存储器

由于嵌入式内存比传统的eNVM更具优势，因此已经针对嵌入式非易失性内存（eNVM）应用进行了深入的研究。具有嵌入式EM（eEM）的微控制器的产量有限，但eEMs市场尚未起飞。如今，先进的数字CMOS技术进行的颠覆性创新为进行根本性变革提供了诱人的动力，从而为eEM提供了巨大的成功机会。相变存储器（PCM）在独立存储器中已被证明是各种EM中最成熟的。本文说明了PCM在eNVM领域的巨大潜力。本文对嵌入式PCM（ePCM）的发展进行了回顾，为扩大工作温度范围以涵盖汽车任务概况所付出的努力提供了证据。
