Abstract

As one of the most promising candidates for next-generation nonvolatile memory, phase change memory is still facing the problem of high power consumption required to reset the device. The melt-quench process during amorphization leads to thermal crosstalk between devices as well. In this work, a paired pulses (P.P.) RESET operation scheme has been demonstrated to reduce the maximum temperature during the amorphization process, which in turn significantly reduces the power consumption. Experiments show that both the minimum RESET programming voltage and power consumption have decreased by up to 0.4 V and 60%, respectively. This proposed programming strategy is promising to optimize the device endurance and stability without sacrificing operating speed.

使用成对脉冲 RESET 操作方案的基于 GST 的密闭相变存储器可节能高达 60

作为下一代非易失性存储器最有前途的候选产品之一，相变存储器仍然面临着复位器件所需的高能耗问题。非晶化过程中的熔淬工艺还会导致器件之间的热串扰。在这项工作中，我们展示了一种成对脉冲（P.P. ）RESET 操作方案，它可以降低非晶化过程中的最高温度，从而显著降低功耗。实验表明，最小 RESET 编程电压和功耗分别降低了 0.4 V 和 60%。这种拟议的编程策略有望在不牺牲运行速度的情况下优化器件的耐用性和稳定性。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
