| Abstract | Traditionally, floating gate (flash) transistors have been used exclusively to implement non-volatile memory in its various forms. Recently, we showed that flash transistors can be used to implement digital circuits as well. In this paper, we present the details on the realization and characteristics of the block-level flash-based digital design. The current work describes the synthesis flow to decompose a circuit block into a network of interconnected FCs. The resulting network is characterized with respect to timing, power and energy, and the results are compared with a standard-cell based realization of the same block (obtained using commercial tools). We obtain significantly improved delay (0.59×), power (0.35×) and cell area (0.60×) compared to a traditional CMOS standard-cell based approach, when averaged over 12 standard benchmarks. It is generally rare that a circuit methodology yields results that are better than existing commercial standard-cell based flows in terms of delay, area, power and energy, and in this sense, we submit that our results are significant. Additional benefits of a flash-based digital design is that it allows for precision speed binning in the factory, and also enables in-field re-programmability (we note that our flash-based design is not an FPGA, but rather an ASIC style design) to counteract the speed degradation of a design due to aging. These benefits arise from the fact that the threshold voltage of flash devices can be controlled with precision. |

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.
