Overview of non-volatile memory Technology: markets, technologies and trends
Advances in Non-volatile Memory and Storage Technology, 2014Co-Authors: Roberto Bez, Agostino PirovanoAbstract:Abstract: In the last decade, the impressive growth of the portable systems market has attracted the interest of the semiconductor industry in non-volatile memory (NVM) technologies for both code and mass storage applications. The current NVM mainstream is based on Flash Technology and it is expected that NOR and NAND Flash will be the high volume NVM production for several years. There is industrial interest in alternative technologies that exploit new materials and concepts to go beyond Flash Technology, to allow better scaling and to enlarge memory performance. We review the current status of charge-storage based Flash memory Technology and introduce the most promising alternative memory concepts. Expected trends and future perspectives are also discussed.

Non-volatile memory technologies: emerging concepts and new materials
Materials Science in Semiconductor Processing, 2004Co-Authors: Roberto Bez, Agostino PirovanoAbstract:The current mainstream, based on the Flash Technology, is expected to be the reference Technology also for the next few years. Nevertheless Flash has technological and physical constraints that make more difficult their further scaling. In this contest there is the industrial interest for alternative technologies that exploit new materials and concepts to go beyond the Flash Technology, to allow better scaling, and to enlarge the memory performance. The main emerging non-volatile memory technologies based on inorganic material, like ferroelectric memory (FeRAM), magnetoresistive memory (MRAM) or phase change memory (PCM) and the main innovative concepts based on organic material like ferroelectric or conductance switching polymer will therefore be analysed. We will then focus the attention on PCM Technology as one of the best candidate as next-decade non-volatile memory Technology, covering the main characteristics and presenting the latest development results.

Screening for Human Immunodeficiency Virus, Hepatitis B Virus, Hepatitis C Virus, and Treponema pallidum by Blood Testing Using a Bio-Flash Technology-Based Algorithm before Gastrointestinal Endoscopy.
Journal of clinical microbiology, 2016Co-Authors: Zhou Jun, Chen Zhen, Zhang Quiuli, An Yuanqi, Verónica Vocero Casado, Yuan FanAbstract:ABSTRACT Currently, conventional enzyme immunoassays which use manual gold immunoassays and colloidal tests (GICTs) are used as screening tools to detect Treponema pallidum (syphilis), hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus type 1 (HIV-1), and HIV-2 in patients undergoing surgery. The present observational, cross-sectional study compared the sensitivity, specificity, and work flow characteristics of the conventional algorithm with manual GICTs with those of a newly proposed algorithm that uses the automated Bio-Flash Technology as a screening tool in patients undergoing gastrointestinal (GI) endoscopy. A total of 956 patients were examined for the presence of serological markers of infection with HIV-1/2, HCV, HBV, and T. pallidum. The proposed algorithm with the Bio-Flash Technology was superior for the detection of all markers (100.0% sensitivity and specificity for detection of anti-HIV and anti-HCV antibodies, HBV surface antigen [HBsAg], and T. pallidum) compared with the conventional algorithm based on the manual method (80.0% sensitivity and 98.6% specificity for the detection of anti-HIV, 75.0% sensitivity for the detection of anti-HCV, 94.7% sensitivity for the detection of HBsAg, and 100% specificity for the detection of anti-HCV and HBsAg) in these patients. The automated Bio-Flash Technology-based screening algorithm also reduced the operation time by 85.0% (205 min) per day, saving up to 24 h/week. In conclusion, the use of the newly proposed screening algorithm based on the automated Bio-Flash Technology can provide an advantage over the use of conventional algorithms based on manual methods for screening for HIV, HBV, HCV, and syphilis before GI endoscopy.

Bit Cost Scalable (BiCS) Flash Technology for future ultra high density storage devices
Proceedings of 2010 International Symposium on VLSI Technology System and Application, 2010Co-Authors: Akihiro Nitayama, Hideaki AochiAbstract:We've developed Bit Cost Scalable (BiCS) Flash Technology as a three-dimensional memory for the future ultra high density storage devices, which extremely reduces the chip costs by vertically stacking memory arrays with punch and plug process. We've advanced it to Pipe-shaped BiCS Flash memory with U-shaped NAND string, improving the operation window and the reliability and realizing the Multi-Level-Cell (MLC) operation. The functionality has been successfully demonstrated using the 32 Gbit test chip with the 16 stacked layers and the MLC operation by 60nm P-BiCS Flash Technology.
