The material screening and qualification is performed through optical reflectivity and 4-probes resistivity measurements. Electrical performances are then investigated through tests of lance-cell analytical PC memory cells. Reset current densities of GST and GeTe are comparable, while GeTe data-retention at high- temperature is significantly improved compared to GST, suggesting that GeTe-based compounds are promising candidates for embedded PC memory applications.","PeriodicalId":113507,"journal":{"name":"2009 IEEE International Memory Workshop","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132541933","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}
