Meet Gurtej Singh Sandhu, the Indian-origin Sikh scientist whose innovation in semiconductor technology has earned him over 1,299 U.S. patents, placing him ahead of Thomas Edison. Living in Boise, Idaho for nearly three decades, Sandhu has quietly revolutionized the world of memory chips through his pioneering research at Micron Technology.
Born in London to Indian parents, Gurtej completed his electrical engineering degree in India and moved to the United States to pursue a PhD in Physics at the University of North Carolina at Chapel Hill. His focus: integrated circuits—the foundation of modern electronics.
Choosing Micron – The Road Less Traveled
In 1989, as Gurtej neared the end of his PhD, he was offered two jobs: one from Texas Instruments, an industry giant, and another from a lesser-known company named Micron Technology. Despite Micron’s small size and risk of failure, he chose them, inspired by their ambitious vision to become the world’s best.
A professor had advised him: “At Micron, you’ll have the freedom to solve real problems. Even if it fails, you’ll gain experience that no boxed-in job can offer.” That freedom became the spark that ignited Sandhu’s innovative career.
Revolutionizing Memory Technology
Once at Micron, Gurtej contributed to sustaining Moore’s Law—the prediction that the number of transistors on a chip would double every year. He developed methods to increase memory density, improve efficiency, and eventually moved into 3D memory stacking, a game-changing technology still being perfected today.
Every patent he developed—often in collaboration with others—earned recognition and bonuses. But the real reward, he says, is knowing his inventions are used across the globe.
More Than Just Patents
Despite holding more U.S. patents than most people in history, Sandhu remains grounded. He has mentored engineering students and faculty at Boise State University for over 15 years. According to Will Hughes, director of BSU’s Micron School of Materials Science and Engineering: “He has tremendous humility and a global perspective on emerging technologies.”
His commitment to community extends to family. Sandhu and his wife, Sukesh, raised two sons—Gureet, a buyer at Albertsons and part-time DJ, and Sunny, who lives and works in Australia.
Overcoming Bias and Stereotypes
Being a Sikh in a predominantly white city like Boise hasn’t always been easy. After 9/11, a woman reported him to the police simply for wearing a turban while driving an SUV. Gurtej took it in stride, laughing about it later with colleagues.
“There is no place in the world where a minority never feels uncomfortable,” he says. “But the U.S., despite its flaws, is still one of the best places for fairness and opportunity.”
The Rise of Micron and a Legacy of Innovation
Micron has also transformed dramatically. Once a manufacturing hub, the Boise campus now focuses on research and development. Though fewer chips are made there, the innovation happening on-site is critical to global memory supply. Sandhu estimates that half of Micron’s engineers in Boise today are international.
Micron’s competitors, many of whom were government-subsidized, couldn’t survive the tech race. Now, only Micron, Samsung, and SK Hynix dominate 95% of the world’s DRAM market.
“All our lives we waited for this day,” says Sandhu. “To see a level playing field where hard work and innovation win—it’s a dream come true.”
Shaping the Future with AI and Beyond
With the rise of artificial intelligence, autonomous vehicles, and big data, memory demands are skyrocketing. That means Sandhu’s work isn’t slowing down. As processes evolve and technology gets more complex, he remains at the forefront, innovating for a smarter future.
“A few years ago, I passed Edison in patents,” he says modestly. “But my real reward is seeing people across the world use the technologies I helped create.”
Gurtej Singh Sandhu’s journey is a testament to what talent, faith, and perseverance can achieve. From a small-town student in India to a world-renowned inventor in Idaho, he represents the spirit of global innovation—and proves that Sikhs can wear turbans and change the world.
