Such faults model pattern sensitivities involving 4 or 5 cells, respectively, when nothing is known about the mapping from logical cell addresses to physical cell locations. The generated tests are thus unaffected by cell re-arrangements resulting from multiple vendors, decoder address scrambling, and repair using redundant cells. Using a parallel test mode, all sub-arrays in a RAM can be tested together even if each sub-array has a different cell arrangement. The generator consists of one 60 K transistor semicustom IC and one 4 Mbit look-up PROM.<<ETX>>","PeriodicalId":248811,"journal":{"name":"Records of the 1993 IEEE International Workshop on Memory Testing","volume":"99 3 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":"132324927","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}
