Features of the novel memory make it suitable for universal memory applications. Besides, as the evolution of information technology, embedded systems with media applications for portable devices are more important in modern life. In both of the perspectives mentioned above, a processing element called arithmetic logic unit (ALU) cluster intellectual property (IP) is designed and implemented to be integrated with MRAM and the platform baseboard in this work. To stack these components such as an ALU cluster, MRAM and versatile baseboard provides a development, verification and demonstration platform for the highly-expected MRAM. The proposed ALU cluster IP with advanced microcontroller bus architecture (AMBA) interface is taped out using TSMC 0.15 um technology and operates at 100 MHz. The chip area is 3.9*3.9 mm2 and gate count is 0.2 million. A 4-layer FRP printed circuit board (PCB) is designed and fabricated as the daughter card for system integration. The daughter card carries the designed chip is integrated to ARM versatile platform board and the PCB of MRAM as the system integration and application development environment.","PeriodicalId":422226,"journal":{"name":"2007 IEEE International Workshop on Memory Technology, Design and Testing","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116079836","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, we develop a novel scheme to highly improve the resolution by applying current test in power-gating sleep mode. A novel fine-grain power-gated adaptive-retention memory cell structure in the double threshold technology is designed for current testability. An LSB-selected decoder is also developed for fast test generation. Analyses on transistor level bridging faults prove the test effectiveness. The proposed scheme can explore the current resolution improvement up to the generic switch intensity ratio of the double threshold-voltage CMOS technology. From simulations in a 0.13 mum technology, the current resolution can be improved by about 40 dB, i.e., 100 times. Once current test can be renascent for embedded memory, the test time can be dramatically reduced.","PeriodicalId":422226,"journal":{"name":"2007 IEEE International Workshop on Memory Technology, Design and Testing","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127243587","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}
