One phase is a high-resistance amorphous phase that is obtained by melting a small volume of glass using ohmic heating, and then quenching it. The second phase is a low-resistance crystalline phase that is obtained by heating the glass to just below the melting point to promote recrystallization. This paper describes two models for such a cell. The first is a very simple single-element, lumped model that exhibits correct phase transition behavior, but is unrealistic in its sensitivity to the heating current pulses. The second, multiple-element model is able to more realistically represent cell heating and cooling behavior, and appears to be the more suitable basis for an electrical simulation model.","PeriodicalId":412381,"journal":{"name":"Records of the 2003 International Workshop on Memory Technology, Design and Testing","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133052421","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 new design exploits hierarchical, multidivided bitlines to offset the reduction in noise margins caused by multilevel signaling and thereby better preserve the signal-to-noise ratio. The multiple sensing operations required to recover multilevel data are performed serially to re-use sense amplifiers and hence minimize the area overhead of the peripheral circuitry at the cost of increased total read time. In a variation of the proposed design, a subset of the addressed row of cells is read in one sensing step while the remaining cells are recovered later in further sensing steps.","PeriodicalId":412381,"journal":{"name":"Records of the 2003 International Workshop on Memory Technology, Design and Testing","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130864909","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}

Commercial memory compilers have their limitation-a large memory may need to be implemented with multiple small memories, if generated by memory compilers. In this paper we introduce a testability-driven memory optimizer and wrapper generator that generates BISTed embedded memories by using a commercial memory compiler. We describe one of its key components called MORE (for Memory Optimization and REconfiguration). The approach is cost effective for designing embedded memories. By configuring small memory cores into the large one specified by the user and providing the BIST circuits, MORE allows the user to combine the commercial memory compiler and our memory BIST compiler into a cost-effective testability-driven memory generator. The resulting memory has a shorter test time, since the small memory cores can be tested in parallel, so far as the power and geometry constraints are considered. As an example, the test time of a typical 256 K/spl times/32 memory generated by MORE is reduced by about 75%.","PeriodicalId":412381,"journal":{"name":"Records of the 2003 International Workshop on Memory Technology, Design and Testing","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115305778","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}

However, the associated surging test time due to increased SRAM capacity is becoming a major challenge when testing either standalone or embedded SRAMs. This paper refines the functional fault models translated from defect simulations for embedded SRAMs with IFA proposed and described. Reconsidering the defect causes of the functional faults allows us to simplify the functional fault model FFM2 and formulate the test time required for detecting Data Retention Faults. We combine this simplification with the consideration of specific memory redundancy elements to develop a new March 6N Test algorithm. Simulation results reveal that our proposed fault modeling and test generation algorithm can reduce total test time to one half or less of that required by the methodology, while maintaining the same defect and fault coverage.","PeriodicalId":412381,"journal":{"name":"Records of the 2003 International Workshop on Memory Technology, Design and Testing","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128836452","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}
