As evolutionary approaches to scaling reach fundamental limits, various new devices are extensively researched and are at different levels of maturity. The link between high performance logic and high density memory has always been a major factor in computing and communication architectures. In the future, this link will be even more crucial to obtain performance gains, particularly for low power applications. In this presentation, speaker will try to answer basic questions such as (1)What are the cost/performance characteristics required to add significant value in computing devices? (2) For some of the leading emerging memory candidates, what materials improvements are needed to realize this value?
