Dr. Jaihyuk Song is the Corporate President & CTO of Samsung Electronics’ Device Solutions Business leading the Semiconductor R&D Center.

Prior to his appointment as the President and CTO, Dr. Song served as EVP and Head of Semiconductor R&D Center responsible for managing a broad range of semiconductor R&D activities from fundamental research to chip level testing, and driving innovation in DRAM, NAND Flash, Advanced Logic and Package, as well as New Memory and CIS device technology development.

Dr. Song started his career as a DRAM process engineer at Samsung in 1996, and has held several management positions in Flash Memory Product & Technology Development at Samsung’s Memory Business. Before joining the R&D Center, he has been mainly responsible for driving the company’s NAND Flash Memory technology development. Starting with the planar 2D structure in 2004, and the revolutionary vertical 3D structure in 2013, which has become an industry-standard since its groundbreaking introduction, he has played a key role in pioneering V-NAND technology solutions for seven consecutive generations.

A veteran within the semiconductor ecosystem, in April 2024, Dr. Song was awarded by the Korean Federation of Science and Technology Societies, the Science and Technology Medal of Innovation "for his devotion and contribution to the Korean semiconductor industry during the last 33 years, by exerting technology leadership from process development to mass production." And was also elected to join the National Academy of Engineering of Korea. In 2017, he received the Korea Technology Award (Presidential Award) from the Ministry of Trade, Industry and Energy in recognition of his work on the 64‑layer, 4th‑generation V‑NAND solution. Building on that pioneering effort, he continued to drive innovation in semiconductor manufacturing, and in April 2024 he was honored with the Science & Technology Innovation Medal by the Ministry of Science and ICT for establishing a world‑leading AI‑DT‑converged intelligent‑factory system that significantly advanced Korea’s semiconductor production capabilities. 

Dr. Song holds a doctoral and master’s degrees in Electrical Engineering from Seoul National University, and a bachelor’s degree in Electrical Engineering from the Korea Advanced Institute of Science and Technology (KAIST).
