| Abstract | Once largely the domain of space-borne applications, the effects of high energy charged particles on electronics systems are now also a concern for conventional terrestrial devices. The configuration memory within reconfigurable components, such as SRAM-based field-programmable gate arrays are particularly vulnerable to radiation-induced single event effects. We present a silicon on insulator (SOI)-based configuration memory system for use in a radiation hard reconfigurable system. A nonvolatile storage cell, able to be manufactured in a standard single polysilicon SOI CMOS process with no special layers, is combined with a Schmitt amplifier, which results in a final structure that exhibits two unique characteristics enhancing its resistance to radiation. First, it is impossible for a radiation-induced event to permanently flip the configuration state. Second, a partial de-programming resulting in a reduction in the magnitude of the storage cell voltage causes a large change in static current that can very easily be detected using a conventional sense amplifier. A simple current detector of the type used in conventional RAM circuits allows the configuration memory to be set up to exhibit self-correcting, or “auto-scrubbing” behavior. Failure estimates indicate a mean time between failures for a single cell to be in the order of 1034 years. |

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.
