论文摘要
我们开发了脉冲引起的现象学理论，该理论在集合背后（从高电阻状态到低电阻状态）和在非挥发性记忆中重置（向后）过程。我们表明，在现代设备中，两者都在绝热状态下演变，能量沉积时间比热化的时间短得多。但是，它们的操作模式不同：用于设置的电压源驱动和当前源驱动的重置。特征温度和过渡速率通过材料和过程参数表示。
We develop a phenomenological theory of pulse induced phase transformations behind the SET (from high to low resistive state) and RESET (backward) processes in nonvolatile memory. We show that in modern era devices, both evolve in the adiabatic regime with energy deposition time much shorter than that of thermalization. They are however different by the operating modes: voltage source driven for SET and current source driven for RESET. The characteristic temperatures and transition rates are expressed through material and process parameters.
