| Abstract | The bathtub curve is widely used in the reliability world to illustrate three characteristics of the system (or an IC) failure rate curve: the early failure rate during initial phase of life, the intrinsic random constant failure rate in the use life, and the wear-out phase at the end-of-life (Reddy, 2003). The bottom part is usually characterised by a constant failure rate expressed in FIT (failure in time, which is 1 failure in 109 device hours). As systems become more and more complex, more and more redundancy and EDAC (error detection and correction, also called error correction code ECC) are implemented in order to improve the system robustness and reliability (Slayman, 2003 and Ziegler and Puchner, 2004). By studying the data retention failure rates of Flash products with ECC, we found that the bottom part of the bathtub (used to be characterized by "random constant failure rate") is not flat. We suggest replace the FIT number by a cumulative failure fraction with a certain time stamp. |

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.
