One such procedure, using measurements of SRAMs and a computer-generated defect-fault dictionary, is presented in this paper. The discussion is focused on the 'resolution of diagnosis', which is the ability to resolve as large a variety of defects as possible. To assess the resolution limits, an experiment involving dictionary generation and SRAM testing was conducted. The test results were compared against simulated bitmaps, and the differences were analyzed using failure analysis. The results obtained confirmed that defect simulation-based diagnosis can be very effective. It can also be enhanced if appropriate SRAM designs, testing strategies and defect models are chosen.<<ETX>>","PeriodicalId":248811,"journal":{"name":"Records of the 1993 IEEE International Workshop on Memory Testing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130733138","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}

Behavior of two different ECL storage element implementations are examined in the presence of physical faults. While fault models for some implementations of CMOS storage elements have been examined, not much attention has been paid to ECL storage elements. The conventional stuck-at fault model termed minimal fault model assumes that an input (output) of a storage element can be stuck-at-1 or 0. The minimal fault model may not model the behavior under certain physical failures in a storage element. The enhanced fault model providing higher coverage of physical failures is presented.<<ETX>>","PeriodicalId":248811,"journal":{"name":"Records of the 1993 IEEE International Workshop on Memory Testing","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114763045","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 paper, the authors propose a current testing for CMOS static RAMs. Firstly, to see what influence a fault has on a power supply current, they analyze the behavior of a single memory cell when a fault occurs. It is found that almost all faults affect power supply current when a write operation is executed. Based on this analysis, secondly, the authors discuss a current testing scheme, where an address decoder structure is modified such that a write operation can be simultaneously executed on all the memory cells in a testing mode. In this current testing scheme, since the whole memory cell array could be treated as if it were a single memory cell, the length of the test sequences is not dependent on the size of memory cell array and must be very short. Hence, the authors believe their current testing method is a promising candidate for testing CMOS static RAMs.<<ETX>>","PeriodicalId":248811,"journal":{"name":"Records of the 1993 IEEE International Workshop on Memory Testing","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126000467","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}
