This configuration uses double coding-point cells and makes the ROM units more fail-safe by using additional fault-detection circuits. An expanded application of the proposed redundancy scheme to programmable logic arrays (PLAs) consisting of AND-ROM and OR-ROM pairs is proposed. If applied to a 256-kb ROM and a 49-k program-point PLA using 1.5- mu m CMOS technology, it is estimated that the proposed redundancy reduces the effective circuit area for defect occurrence to 16% of that of the nonredundant basic circuit module for the ROM, and to 9% for the PLA.<<ETX>>","PeriodicalId":377227,"journal":{"name":"1993 Proceedings Fifth Annual IEEE International Conference on Wafer Scale Integration","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124133338","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}

Some of the criteria for picking the value of the bypass capacitance are examined, together with techniques for introducing high-dielectric-constant materials into the processing of the semiconductor substrates. The possibility of depositing thin layers of amorphous BaTiO/sub 3/ at low temperature to form a reliable, pin-hole free dielectric for bypass capacitance by use of ionized cluster beam techniques is explored. Deposition of the amorphous material on both metal and semiconductor substrates is possible.<<ETX>>","PeriodicalId":377227,"journal":{"name":"1993 Proceedings Fifth Annual IEEE International Conference on Wafer Scale Integration","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114443860","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}

Each time a processor fails, soft switching can be used to bypass either a row or column and a degraded performance functional array can be maintained. Processor to processor communication delay may increase with each processor failure, and the entire array will eventually fail if the delay exceeds a predetermined limit. The impact of reconfiguration on fault tolerant WSI processor array performance is examined. The analysis considers interconnect length, communication delay, and maximum operating frequency.<<ETX>>","PeriodicalId":377227,"journal":{"name":"1993 Proceedings Fifth Annual IEEE International Conference on Wafer Scale Integration","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115593888","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}
