The cross-over between top and bottom electrodes of RRAM forms the metal-insulator-metal sandwich structure. The electrical responses of RRAM are studied in detail, including forming process, SET process and RESET process. The correlations between SET voltage and RESET voltage, high resistance state and low resistance state are dis- cussed. The electrical characteristics of RRAM are in a strong relationship with the compliance current in the SET process. The conduction mechanism ofnano-scale Hf/HfO2-based RRAM can be explained by the quantum point contact model.展开更多

文摘G.N.Leech(1983)针对H.P.Gricc的合作原则而提出了礼貌原则(Politeness Principle),对于其中最重要的一条准则--Tact Maxim,何自然等译成"得体准则".刘润清等译成"策略准则",当笔者有幸阅读Leech原著"Principles of Pragmatics"(<语用学原则>)时,发现这两种译文都同原文似有出入.
