Endurance degradation model applicable to the broad node range of floating-gate NAND flash memory is proposed for the first time. The model is based on generation of the trapped charge, which follows nonuniform spatial distribution of the erase tunne

An attenuated phase shift mask (PSM) (half-tone PSM) is an effective and common technique for resolution enhancement and for forming specific patterns. When an ArF-attenuated PSM with hole- or space-type patterns is used under a KrF light source scan

In this paper, we have developed a new floating-gate-type Flash cell compact model based on the channel potential by using PSP metal-oxide-semiconductor description. Cell-to-cell coupling, Fowler-Nordheim tunneling, and new leakage current formulas h
Debris flows caused by heavy rainfall in mountain areas near expressways lead to severe social and economic loss and sometimes even result in casualties. However, in Korea, the design of road structures that resist these debris flow incidents are gen

We investigated the intrinsic variation of retention in phase-change memory using a phase-field method that is capable of depicting stochastic nucleation followed by the growth of the nucleated crystallites. We found that the median of the retention

In this letter, a cost-effective vertical diode scheme for next-generation memory devices, including phase-change memories (PCMs), is realized. After the contact formation for diodes with only one mask layer, an amorphous silicon (a-Si) film was depo
