| Abstract | High density Non Volatile Memory (NVM) requires large threshold window and small leakage current which will decrease detrapping of charge from storage dielectric. In order to achieve this, a novel device structure called side block oxide band gap engineered SONOS(SBO-BESONOS) is proposed. SBO-BESONOS overcomes the short channel effects when device size is reduced to nanometer regime. The side block oxide suppresses source/drain electric field interference with channel conduction. It reduces leakage current significantly and increases gate controllability over the channel. The band gap engineering improves retention >10yrs with large threshold window >4V and a small gate voltage. This device can be used for Multi Level Cell(MLC) applications where high bit density is required. The side block oxide improves device performance at elevated temperature. The device characterization delivers promising results in terms of threshold window, retention, leakage current and programming threshold and also fully compatible with state-of-the-art CMOS technology. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
