ReRAM technology is complex and multi-faceted, encompassing expertise from an array of disciplines. Since the early 2000s, when the industry first saw that Flash would ultimately have scaling issues, many companies have tried – and failed – to deliver a commercial replacement for Flash.

Now, as we see the world’s leading foundry placing its NVM bets for the future on Resistive RAM (ReRAM or RRAM), I thought I would share what goes into creating such a technology.

To be able to bring up a successful ReRAM technology that is both optimized for performance and commercially viable, a company requires four key elements. With only one or two or even three of these ‘pillars’ of success, a company cannot provide a strong technology which fully addresses the needs of the market. Each of these pillars represents a domain of expertise that is inherent to developing and optimizing the solution, and each domain requires a very different skillset and know-how.

In this article, I will describe these four pillars, explain how each contributes to enhancing the technology and how, when combined under the same roof, results in an optimized solution.
