This paper presents a capacitor-less 1T DRAM cell transistor with high scalability and long retention time. It adopts gate to source/drain non-overlap structure suppress junction leakage, which results in 80 ms time at 85degC length of 55 nm. Compared the previous reports, proposed shows twice longer even though shrinks half them. By TCAD analysis, we have confirmed that improvements are attributed superiority device structure.
Purpose: As the construction industry accounts for a significant portion of global carbon dioxide emissions, importance reducing emissions through remodeling existing buildings is being emphasized. This study proposes method to evaluate greenhouse gas each building material in process by integrating BIM and LCA, visualizing this model. Method: Using models, quantity cost are calculated, evaluated LCA. Then, these visualized model using Dynamo-based parametric algorithm. analyzed total five...
One of the most important issues for DRAM development is control data retention time. A negatively-biased off-state level word line (NWL) was introduced to memory cell design improve transistor "on" current and maintain "off sufficiently low. This paper discusses a method NWL bias time in with NWL.
Cavitation phenomena in pumps are major determinants of the lifespan both impeller and pump itself, causing significant vibration noise, which critical concerns for designers. This study focuses on influence various geometric factors impeller, including shape blade leading edge, inlet angle, number thickness blades, surface roughness, wrap outlet width, hub diameter, tip clearance. The analyzed this study, exhibited issues noise actual industrial settings, was evaluated by varying only...
A new type diffractive spatial optical modulator has been developed for laser projection display. It inherent advantages such as fast response time and high-performance light modulation characteristics. Also, it is suitable embedded mobile display module because of its compact volume (≤20cc) low power consumption ( 2.0W).≤
