| Abstract | Since Pohm introduced the concept of multiturn windings as a means for improving the efficiency of planar thin film memory elements and thereby lowering the cost, very little, work has been published on memories using this technique. Planar thin film memory elements typically require word currents on the order of 500 ma and bit currents on the order of 150 ma while signals are in the range of 1 to 2 mv. Multiturn windings can be used for sense lines and/or word lines to improve the efficiency of planar film elements because the drive requirements are inversely proportional to the number of turns while the signal output is theoretically directly proportional to the number of turns. This paper describes the design of a 74000 bit planar thin film memory using a multiturn sense-digit structure but using single lines for word drive. |

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.
