| Abstract | In this paper, a novel NAND Flash Memory Controller was designed. A t-EC w-bit parallel BCH ECC code was designed for correcting the random bit errors of the flash memory chip, which is suitable for the randomly bit errors property and parallel I/O interface of the NAND type Flash memory. A Code-Banking mechanism was designed for the trade-offs between the controller cost and the ISP (in system programmability) support. With the ISP functionality and the Flash Parameters programmed in the reserved area of the Flash Memory chip during the card production stage, the function for supporting various kinds of NAND Flash memory could be provided by a single controller. In addition, built-in defect management and wear-leveling algorithm enhanced the product life cycle and reliability. Dual Channel accessing of the Flash memory provided the good performance in data transfer rate. With respect to the proposed controller architecture, a real SD/MMC flash memory card controller chip was designed and implemented with UMC 0.18mum CMOS process. Experimental results show the designed circuit can fully comply with the system specifications and shows the good performances. |

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.
