| Abstract | With its fast write and read, small cell size, non-volatility and excellent endurance, Spin Transfer Torque-RAM STT-RAM) has a high potential of dominating the embedded and standalone memory world in the near future. In this paper, the suitability of different classes of magnetic materials constituting the STT-RAM free layer is reviewed for faster switching and thermal stability. We identify the following material classes for faster switching in the thermally stable free-layer of a STT-RAM: (a) In-plane materials with high H and low M. While the high H deters the magnetization during the easy to hard axis switching, it helps with switching past the equator, making the switching speeds for high and low H materials comparable. However, high H materials benefit from higher thermal stability. (b) Perpendicular materials with low damping have the same switching speed as in-plane materials but greater switching probability because of a lower critical current. The demagnetization field helps the free layer to start switching to the hard axis, but hinders it from switching further to the easy axis beyond the equator. (c) Anti-ferromagnetically capped partially-perpendicular materials. Capping with a Va layer decreases the demagnetization field, which promotes faster switching. |

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.
