The Future of Memory Chip technology

By Dr. Gurtej S Sandhu, Principal Fellow and Vice President, Technology Development, Micron

A commitment to innovation and creativity at a system level is required to meet demands of this data age. These innovations will help fuel the next generation of capabilities in generative artificial intelligence (GenAI) and enable technologies such as self-driving cars, smart medicine, industrial automation, space exploration etc. which sounded like science fiction not so long ago. Several new memory technologies have been proposed over the years with no clear winners. Some of the critical factors which need to be considered for a successful implementation of a new technology include why and when alternate memory technologies may be needed, what are the performance criteria and related requirements, and what needs to happen in the ecosystem to support a successful new technology. The result of this reality is that bottoms up development for a new memory technology may not feasible and we must target application-specific solutions for future markets.
