IBM has unveiled a new chip technology that stacks transistors vertically, potentially extending Moore’s Law for another decade. By building up, rather than shrinking, transistors, the company has created a chip with 100 billion transistors on a fingernail-sized area, twice the density of its previous technology. This new architecture, known as a nanostack, is energy-efficient and can do 50% more work in the same time. It’s a transformational leap forward that could have a significant impact on the tech industry. Why it matters: This technology could lead to faster, more efficient computers that will power the next generation of AI and other applications.
