However, 3D RRAM still suffer from poor endurance especially during high speed operation which limits its extensive applications. Here, we report the transient control method which enables a significant improvement of device stability and endurance. We demonstrated the stable transient control under the fast pulse switching in RRAM cells with different sizes of 1 μm and 200 nm. Endurance higher than 107 cycles are achieved while keeping the ratio of high/low resistance level at 103. High speed switching with 1 ns pulse width can be achieved. We unveil the material switching dynamics responsible for the stable transient process, which is responsible for the higher endurance for RRAM devices.","PeriodicalId":441941,"journal":{"name":"2016 International Symposium on VLSI Technology, Systems and Application (VLSI-TSA)","volume":"275 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114379776","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}

The device is a single-gate, flat-channel TFT charge-trapping device with ultra-thin body. The ultra-thin body TFT device enables tight initial Vt distribution as well as excellent short-channel effect that is comparable to and sometimes superior than the more prevailing gate-all-around (GAA) macaroni devices of other 3D NAND architectures. Unlike GAA device for which the electric field is a function of channel hole curvature, the flat cell is insensitive to etching CD, thus SGVC device is very tolerable to the non-ideal vertical etching and has shown superb layer-to-layer device uniformity. Even without help from curvature (like in GAA) our SGVC flat cell achieves excellent P/E window of >10V with only modest interferences that can support TLC (3 logic bits per cell) operation. Owing to the double-density in a single WL trench and much more efficient array design with minimal overhead, SGVC architecture offers 2 to 4 times memory density than GAA VC 3D NAND at the same stack layer number.","PeriodicalId":441941,"journal":{"name":"2016 International Symposium on VLSI Technology, Systems and Application (VLSI-TSA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133447661","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}
