For the past decades, the density of DRAM has been remarkably increased by making access transistors and capacitors smaller in size per unit area. However, shrinking devices far beyond the 10 nm process node increasingly poses process and reliability challenges. As Flash technology made a pivotal and successful innovation via 3D NAND, DRAM technology may also adopt vertical stacking memory cells. Vertically stacked DRAM (VS-DRAM) continues to increase bit density on a die by increasing the number of layers along with reducing the size of the transistor. In this paper, the opportunities and challenges of VS-DRAM are discussed.

“In June 2003
the scientific and medical communities at MIT Harvard University and its affiliated hospitals and the Whitehead Institute banded together as collaborating partners to form the Eli and Edythe L. Broad Institute based in Cambridge MA. The Broad Institute established with initial funding from a $100 million philanthropic donation from the Los Angeles-based Broad family was primarily viewed as a marriage between the Whitehead Institute's Center for Genome Research (WICGR) and the Harvard Institute of Chemistry and Cell Biology (ICCB). Eli Broad founder and chairman of AIG SunAmerica Inc. explained “the purpose of the Broad Institute is to create a new type of research institute to build on the accomplishments of the human genome project and to move to clinical applications to both prevent and cure diseases.”
Every Thursday morning we meet with perhaps 20 faculty members and 100 other researchers to discuss what we're all doing and should be doing next. -David Altschuler
This paragraph was written five years ago when the Broad Institute was in its very earliest days as a life science research community (McCarthy 2005). Since that time “the Broad” as it's known has kept true to Eli Broad's vision having attracted a talented group of researchers faculty trainees and professional staff. This 1600 person research community known internally as “Broadies” includes faculty staff and students from throughout the MIT and Harvard biomedical research communities and beyond with collaborations spanning over a hundred private and public institutions in more than 40 countries worldwide.
“What is special about the Broad is that we have people from Harvard MIT and the Harvard hospitals come together and work on problems of shared interest that could not be solved in their own individuals labs” explains David Altshuler M.D. Ph.D. Deputy Director and one of the Broad's six core faculty members. “These problems require expertise beyond any one principal investigator and in

Some studies have been performed on the application of the supercritical fluid environment to the extracting separation, the decomposition of the pollutant and the synthesis of the organic compound. One of the problems to apply the supercritical fluid is the selection of the reliable construction material for this environment. Some examinations have been done regarding to the localized corrosion and the stress corrosion cracking, but the electrochemical behavior of metallic materials has not been studied in this environment. The results of the electrochemical examination in the carbon dioxide supercritical fluid mixed with nickel-plating solution, which is acidic and containing chloride, are introduced in this paper. The electrochemical characteristics of the materials in this environment become obvious from this study. It is also estimated from this examination that 329J4L stainless steel and C276 alloy can be use for the construction materials in this supercritical fluid environment.
