One of the promising devices known as memristor is under investigation in order to be used together with deep nanometer CMOS, that has the ability to solve technologies problems. It has emerged in several domains due to its nonlinear behavior, nonvolatility, low power consumption, high density and compatibility with CMOS. Several memristor models have been developed so far. Whereas, a compact model should be flexible and sufficiently accurate. In this paper, an analysis of a memristor model using Verilog-A and SPICE is discussed, in order to elaborate an appropriate model for implementation in CMOS-based circuit applications. It is shown that the proposed Verilog-A model is flexible, accurate and efficient, verified by both electrical simulations and experimentally measured results. It also carries the desired nonlinear memristor fingerprint, an adjustable threshold voltage and the applicability to fit and simulate different switching behaviors. Hence, it is the most suitable for low-power and high-density applications at the industrial levels, which takes advantage compared to other approaches based on SPICE models.","PeriodicalId":342516,"journal":{"name":"2019 IEEE International Conference on Design & Test of Integrated Micro & Nano-Systems (DTS)","volume":"295 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116314779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional materials so far used for RRAM technology suffer from a severe issue related to the temperature increase. In this paper, we investigate the possibility of mitigating such a problem by exploiting the excellent properties of novel nanostructured materials, such as the Carbon Nanotubes (CNTs). To this end, a 3D 1Diode-1RRAM crossbar is here analyzed, comparing conventional Ni metal electrodes to novel CNT ones. Accurate temperature-dependent electrical and thermal conductivities are used to simulate the behavior of the materials. An electrothermal analysis performed by means of a full 3D numerical model of such a structure provides the voltage and temperature distributions over the 3D 1D-1RRAM crossbar. The use of CNT electrodes is demonstrated to provide excellent uniformity in the voltage distribution, good electrical current pathways distribution and a temperature reduction more than 300K over the baseline crossbar design.","PeriodicalId":342516,"journal":{"name":"2019 IEEE International Conference on Design & Test of Integrated Micro & Nano-Systems (DTS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131151820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
