| Abstract | Nonvolatile memories (NVMs) such as flash memories play a significant role in meeting the data storage requirements of today's computation activities. The rapid increase of storage density for NVMs however brings reliability issues due to closer alignment of adjacent cells on chip, and more levels that are programmed into a cell. We propose a new method for error correction, which uses the random access capability of NVMs and the redundancy that inherently exists in information content. Although it is theoretically possible to remove the redundancy via data compression, existing source coding algorithms do not remove all of it for efficient computation. We propose a method that can be combined with existing storage solutions for text files, namely content-assisted decoding. Using the statistical properties of words and phrases in the text of a given language, our decoder identifies the location of each subcodeword representing some word in a given input noisy codeword, and flips the bits to compute a most likely word sequence. The decoder can be adapted to work together with traditional ECC decoders to keep the number of errors within the correction capability of traditional decoders. The combined decoding framework is evaluated with a set of benchmark files. |

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.
