The Segers circuit: An Aggie scaling modern tech and its leaders

Dennis Segers has spent his career at the forefront of technology that powers our modern world. From helping develop early computer memory chips to shaping today’s industry leaders, he hasn’t just watched the tech world evolve — he’s helped build, scale and lead it. 

With 45 years of accomplishments in computing, Segers is a prominent influence in the tech sector. Starting out, however, he was just like any other Texas A&M University student, finding his way on the path to success. 

Early life and discovering engineering

As a first-generation student from small-town Yoakum, Texas, he had little exposure to engineering in his formative years but showed signs of talent. In what he describes as an idyllic childhood, he remembers tearing apart transmissions and rebuilding cars from the age of 13 while excelling in school.

Suffering the loss of his father in his junior year of high school, Segers found himself searching for direction. His high school math and physics teacher, Leroy Munich, took notice of his natural aptitude for engineering. 

“I had this continual debate with my high school math teacher, who kept telling me, ‘Dennis, you’ve got to go into electrical engineering.’ But I had no examples of engineers around me, and I didn’t understand what an engineer did,” he said.

His father had always instilled in him the importance of getting a college education, and Segers decided he had the right idea. Just a couple of hours away with a respected engineering program, Texas A&M sounded like the perfect fit. Before even setting foot on campus, he applied to the mechanical engineering program and began enrolling in courses. However, he quickly realized that his chosen major was not for him, as he was disappointed to find his early classes had little to do with cars. His sense of direction faded.

“I would describe my first two years at Texas A&M as a random walk through the course curriculum. I was just trying to find myself, and did a lot of different things,” he said. “But after my sophomore year, I got married to my high school sweetheart, Debbie Jennings, and she became a strong influence to focus on my education.”

Introduction to electrical engineering

Segers knew it was time to get serious about his studies. In his junior year, he decided to switch majors to electrical engineering. He landed in a course taught by Professor John Dennison called the fundamentals of circuit design. Like his high school teacher, Dennison became the second guiding force in his engineering journey. 

“He had such an incredible joy for teaching that I thought, ‘okay, I like this. I like where I am,’” he said. “That led to me really buckling down in electrical engineering.” 

Soon after, he talked his way into working in the solid state physics laboratory, where his journey with integrated circuits began. 

“I spent every spare moment of my time working as a lab rat. I was unpaid and just happy that they let me in,” he said. “I did a research project there, and that led to falling in love with this whole concept of integrated circuits, which were pretty new at that time.”

He went on to complete his bachelor’s degree in electrical engineering, graduating cum laude, and later completed graduate-level coursework at the University of Dallas and Stanford University. 

Entering the workforce during the birth of integrated circuits

Segers’ hunger for knowledge as a student set him up for success. Landing his first job at Mostek Corporation, he began his career developing some of the earliest computer chips, which went on to shape the industry. He quickly rose into a leadership role, heading up teams that created breakthrough technology used across a wide range of computing systems. 

During that time, he gained firsthand insight into the chip and semiconductor industries, which have become central to modern technology. He then used this experience to co-found and scale Summit Microcircuits, which eventually merged with Benchmarq Microelectronics, where he became vice president of engineering and general manager of the non-volatile products group. There, he oversaw the development of the industry’s first smart battery control integrated circuit. This success launched him into leadership roles at major tech companies that flourished under his direction. 

As CEO of Matrix Semiconductor, he led the pioneering development and commercialization of the industry’s first monolithic 3D integrated circuits, which were adopted as the primary memory chip for the Nintendo DS. He successfully scaled the venture-backed startup to high-volume production before orchestrating its $400 million acquisition by SanDisk in 2006.

Over the course of a 45-year career in high tech, Segers has served on the boards of four public companies and six venture-backed startups. He currently serves as chairman of QuantumScape, a leader in solid-state EV batteries.

Becoming a mentor and industry leader

Segers’ fingerprint on modern computing is expansive and foundational, but his impact reaches far beyond his own accomplishments. In an industry defined by rapid change, his influence has endured through the people he has empowered along the way. He estimates that over 20 people who have worked under his leadership went on to become CEOs, vice presidents, senior executives and key tech leaders. 

“The thing I’m most proud of has been the success of the many young engineers and executives who have worked under me,” he said. “I find it very meaningful when you know somebody who has had a very successful career – in many ways more successful than mine – who comes back and says, ‘Dennis, I just want to thank you for who I’ve become.’ That means a great deal to me.”

As part of his commitment to giving back, Segers shares what he has learned, both formally and informally. He taught engineering management courses as an adjunct lecturer at Santa Clara University for nine years and continues to advise industry leaders across the technology community. He also serves as a long-standing advisor to Texas A&M, is recognized as an Outstanding Alumni Award recipient, and has endowed a professorship and multiple scholarships for first-generation students.
