Memristors possess great application prospects in terabit nonvolatile storage devices, memory-in-logic algorithmic chips and bio-inspired artificial neural network systems. However, "what is the origin state of the memristor?" has remained an unanswered question for half a century. While many applications rely on the memristor, its origin state is becoming a fundamental issue. Herein, we reveal a new state, the pure capacitance state (PCS), which occurs before the memristor is triggered, and the origin state of the memristor can be verified in the memory cells through controlling the ambience parameters. Discovery of the PCS, a missing earlier stage of the memristor, completes the whole evolution map of the memristor from the very beginning to the final developed state.
忆阻器在太比特非易失性存储器件、存算一体算法芯片和类脑人工神经网络系统中有巨大的应用前景。然而,“忆阻器的初始状态是什么?”这个问题半个世纪以来一直没有答案。虽然许多应用都依赖于忆阻器,但它的初始状态正成为一个基本问题。在这里,我们揭示了一个新的状态,即纯电容状态(PCS),它发生在忆阻器被触发之前,通过控制环境参数,可以在存储单元中验证忆阻器的初始状态。PCS 的发现,即忆阻器缺失的早期阶段,完成了忆阻器从初始到最终发展状态的整个演化图。
