Moreover simulations of the electrical field through the tunnel oxide didn't show any change of the maximum value, that means there is no impact on cell reliability. Endurance tests were performed on several memory cells with divide up polarizations.

This method focuses on EEPROM cell geometry automatic generation for a targeted program window including constraints like robustness to process variation, program high voltage and electric field minimization. The method is based on a mathematical model generated with a \"Design Of Simulation\" (DOS) technique. The DOS technique takes as input, simulations results of a floating gale transistor for different given geometries and program high voltages. It produces, as output, polynomial equations of the threshold voltages and maximal electric field injunction of the geometric parameters and of the program high voltage. Using those equations, the design process is realized in two steps. In a first step, a set of cells (geometry and high voltage) meeting a targeted threshold voltages window is generated. From this set of cells, the optimal cell is selected under robustness, high voltage and electric field minimization criteria.","PeriodicalId":230758,"journal":{"name":"Proceedings of the 2002 IEEE International Workshop on Memory Technology, Design and Testing (MTDT2002)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127163346","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}

In this article we describe the results of a simulation study into the effects of crosstalk among DRAM wordlines and bitlines for present and future technology nodes predicted by the roadmap. An analog simulator was used to solve the associated transmission line equations derived from Maxwell's equations in the time domain. Hence, we not only considered interconnect resistances and capacitances, but also inductances and realistic wave propagation effects. The circuit parameters of the simulation models were extracted from standard DRAM geometries implied by the roadmap data. Various bitline-bitline and wordline-wordline coupling scenarios were then studied in simulation. Our results suggest that down until the 22-nm node, single bitline twisting will continue to be effective against bitline-bitline coupling, but that wordline-wordline coupling effects will become more problematic.","PeriodicalId":230758,"journal":{"name":"Proceedings of the 2002 IEEE International Workshop on Memory Technology, Design and Testing (MTDT2002)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127550014","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}

It does so by using more than two possible signal voltages on each cell capacitor thus permitting more than one bit to be stored in each cell. Birk's MLDRAM scheme has several promising properties, including robust locally-generated data signal and reference signal generation, and fast flash-conversion sensing. This paper describes a fault model for Birk's MLDRAM that was developed by considering the behaviors produced by likely defects at the schematic level. The resulting behaviors include faults that are detectable as observable logical errors, faults that can be detected by current measurements, and faults that, in the worst case, can only be detected by testing for degraded noise margins. All Boolean faults in the fault model can be detected by an efficient test whose length grows linearly in the number of cells. The narrower noise margins in MLDRAM will make it more vulnerable to pattern sensitivities. We also developed a linear test that evaluates worst-case sensing conditions.","PeriodicalId":230758,"journal":{"name":"Proceedings of the 2002 IEEE International Workshop on Memory Technology, Design and Testing (MTDT2002)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125137322","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}
