Introduction

Dr. Young-Hyun Jun (Korean: 전영현), born in 1960, is a prominent South Korean business executive and semiconductor expert renowned for his contributions to memory technology and strategic leadership in the electronics industry. As of October 2025, he serves as the Vice Chairman and sole CEO of Samsung Electronics, the world’s largest memory chipmaker and a global leader in consumer electronics. Appointed to this role on March 19, 2025, following the sudden passing of co-CEO Han Jong-hee, Jun oversees the company’s Device Solutions (DS) Division, which encompasses semiconductors, displays, and advanced research. His tenure emphasizes bolstering Samsung’s competitiveness in AI-driven technologies, high-bandwidth memory (HBM), and next-generation manufacturing amid intensifying global rivalry, particularly with competitors like TSMC and SK Hynix.

Under Jun’s leadership, Samsung has accelerated investments in AI semiconductors and sustainable practices, aiming to reclaim market share in DRAM and NAND flash while navigating geopolitical challenges in the supply chain. His engineering background and pragmatic approach have positioned him as a stabilizing force during a transitional period for the company, with analysts praising his focus on innovation and operational efficiency.

Early Life and Education

Jun was born in South Korea in 1960, growing up during the nation’s rapid industrialization in the post-Korean War era. Recognizing the value of education early on—much like his contemporaries in the chaebol (family-run conglomerate) leadership—he pursued a rigorous academic path in electrical engineering, a field pivotal to Korea’s tech boom.

Bachelor’s Degree: B.A. in Electrical Engineering from Hanyang University (Seoul, 1980s).
Master’s and Ph.D.: M.S. and Ph.D. in Electrical Engineering from the Korea Advanced Institute of Science and Technology (KAIST), where he specialized in semiconductor design and materials. His doctoral research likely focused on memory architectures, laying the groundwork for his later innovations in DRAM and flash memory.

Jun’s academic credentials underscore his technical depth, distinguishing him from more finance-oriented executives in Samsung’s upper echelons.

Career Beginnings and Early Achievements

Jun’s professional journey began in 1992 at LG Semiconductor (now part of SK Hynix), where he started as a DRAM (Dynamic Random-Access Memory) developer. This entry-level role immersed him in the cutthroat world of memory chip R&D, honing his skills in process integration and yield optimization during the 1990s Asian financial crisis.

In 1999, LG Semiconductor merged with Hyundai Electronics, forming Hynix Semiconductor. Jun transitioned seamlessly, contributing to recovery efforts post-merger. By 2000, he joined Samsung Electronics, attracted by its aggressive expansion in semiconductors. At Samsung, he quickly rose through engineering ranks, focusing on both DRAM and NAND flash technologies—core to mobile devices, servers, and data centers. His early work involved pioneering high-density memory solutions, authoring numerous technical papers, and securing patents that enhanced Samsung’s edge in energy-efficient chips.

Rise at Samsung: Key Positions and Milestones

Jun’s ascent at Samsung reflects a blend of technical prowess and managerial acumen, spanning over two decades:

2000–2014: Engineering Leadership: As a senior engineer and later executive in the Memory Business Unit, Jun led teams developing cutting-edge DRAM modules and 3D NAND flash. He played a key role in Samsung’s dominance during the smartphone era, enabling breakthroughs like LPDDR memory for devices such as the iPhone and Galaxy series. By 2014, he became President of the Memory Business Division, steering it through volatile cycles and achieving record revenues amid the rise of big data.
2014–2017: President, Memory Business: Under his helm, Samsung solidified its position as the global No. 1 in DRAM market share (over 40% at peaks). He navigated the 2016–2017 memory supercycle, investing heavily in 10nm-class processes that reduced power consumption by up to 30%.
2017–2023: Samsung SDI Era: In a strategic pivot, Jun was appointed President and CEO of Samsung SDI, the company’s battery and display arm, in March 2017. He later became Chairman in 2022. During this period, he expanded SDI’s electric vehicle (EV) battery production, forging partnerships with automakers like BMW and expanding capacity to 200 GWh annually. His leadership grew SDI’s revenue from KRW 12 trillion in 2017 to over KRW 20 trillion by 2022, while advancing solid-state battery R&D. Challenges included the 2021 chip shortage, which Jun addressed through diversified sourcing.
2023–2024: Future Business and DS Head: Returning to Samsung Electronics, Jun headed the Future Business Division (2023–2024), exploring AI and biotech ventures. In May 2024, he assumed leadership of the DS Division, Memory Business, and Samsung Advanced Institute of Technology (SAIT), integrating R&D with commercial operations. This role positioned him to tackle Samsung’s lag in foundry services and HBM for AI GPUs.
2025–Present: Vice Chairman and CEO: Following Han Jong-hee’s death on March 25, 2025, from a heart attack, Jun was elevated to CEO, becoming the de facto head of Samsung’s operations. He reports to Executive Chairman Lee Jae-yong and focuses on “swift, coordinated responses” to stakeholders. Key initiatives include a $200 billion semiconductor investment plan through 2030, emphasizing U.S. fabs and EUV lithography advancements.

Jun has authored dozens of IEEE papers on memory scaling and holds multiple patents. He is a frequent speaker at forums like the World Economic Forum, advocating for collaborative innovation in semiconductors.

Leadership Style and Legacy

Known for his data-driven, engineer-first mindset, Jun prioritizes long-term R&D over short-term profits, often crediting team collaboration for successes. Unlike flashier predecessors, he maintains a low profile, avoiding media spotlight while fostering cross-divisional synergy at Samsung. Critics note his SDI tenure faced EV market volatility, but supporters highlight his resilience in turning around underperforming units.

At 65, Jun represents a generational bridge at Samsung, blending the tenacity of its founding era with modern tech imperatives. His vision centers on “AI everywhere,” positioning Samsung as indispensable in the intelligent computing age.
