Moore’s Law, named after Gordon E. Moore, co-founder of Intel, has been a guiding principle in the field of technology for over five decades. It postulates that the number of transistors on a microchip doubles approximately every two years, leading to exponential growth in computing power. However, as we move further into the 21st century, the validity of Moore’s Law has been increasingly called into question. This article aims to explore the current state of development in regards to Moore’s Law as of 2023.

The Evolution of Moore’s Law

Moore’s Law originated from an observation made by Gordon Moore in 1965. He noted that the number of transistors in a dense integrated circuit had been doubling roughly every year and predicted that this trend would continue for at least the next decade. By 1975, Moore revised his observation, stating that this doubling would occur approximately every two years indefinitely.

For over 40 years, this principle has driven the semiconductor technology revolution, leading to the proliferation of computers and other electronic devices. However, the inherent complexity of semiconductor process technology has been growing, and these complexities have challenged the continuation of Moore’s Law. Transistors have become three-dimensional, and the small feature size of today’s advanced process technologies has required multiple exposures to reproduce these features on silicon wafers. This has added extreme complexity to the design process and has “slowed down” Moore’s Law.

The Current Status of Moore’s Law

As of 2023, the debate over whether Moore’s Law is “dying” or already “dead” continues. While it’s true that chip densities are no longer doubling every two years, Moore’s Law is still delivering exponential improvements, albeit at a slower pace. The trend is very much still here.

Intel’s CEO, Pat Gelsinger, believes that Moore’s Law is far from obsolete. He announced a goal for the next 10 years not only to uphold Moore’s Law but to outpace it. There are many industry veterans who agree with this. Mario Morales, a program vice president at IDC, said he believes Moore’s Law is still relevant in theory. He stated, “If you look at what Moore’s Law has enabled, we’re seeing an explosion of more computing across the entire landscape. It used to be computing was centered around mainframes and then it became clients and now edge and endpoints, but they’re getting more intelligent, and now they’re doing AI inferencing, and you need computing to do that. So, Moore’s Law has been able to continue to really push computing to the outer edge.”

The Future of Moore’s Law

While the consensus is that Moore’s Law is slowing down and that it might soon be augmented, it is still driving improvements in processing technology and the amount of progress that follows these improvements. If Moore’s Law were dead, it simply couldn’t do this.

Moreover, the industry is now faced with a new trend, “More than Moore” (MtM), where added value to devices is provided by incorporating functionalities that do not necessarily scale according to “Moore’s Law.” This methodology complements Moore’s Law and may extend the validity of a renewed Moore’s Law for another decade and beyond.

Conclusion

In conclusion, while the strict definition of Moore’s Law may no longer apply, the spirit of the law – the drive for exponential growth in computing power – is very much alive. Through innovations in process, packaging, and architecture, the industry continues to push the boundaries of what’s possible, ensuring that Moore’s Law, in one form or another, continues to shape the future of technology.
