Abstract(in English) A 'pore engineering', which is a method for controlling the memory performance of conducting-bridge random access memory (CB-RAM) by regarding the polycrystalline oxide memory layer as a nanoporous body, is proposed. This method is intended to control the resistive switching properties by controlling the size, physical and chemical properties of the pores, and by providing an appropriate solvent to pores. In this paper, we confirmed that both forming and set voltages were decreased by providing solvents (water and ion liquids of [bmim][TFSA] and [P_<1ME>][TFSA]) to the HfO_2 layer of Cu/HfO_2/Pt structures. In addition, the relationship of I_∝1/R_ was true independently of types of solvents, suggesting that reset occurs by a common mechanism. On the other hand, I_ decreased remarkably only when water was provided.
