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.

使用配对脉冲 RESET 操作方案，基于 GST 的受限相变存储器可节省高达 60% 的能源


作为下一代非易失性存储器最有前途的候选者之一，相变存储器仍然面临着复位器件所需的高功耗问题。非晶化过程中的熔融淬火过程也会导致器件之间的热串扰。在这项工作中，成对脉冲 （P.P.）RESET 操作方案已被证明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%。这种提出的编程策略有望在不牺牲运行速度的情况下优化设备的耐用性和稳定性。
