Lee Dong-hoon, SK Hynix Vice President, "World's Tallest 4D NAND to Set New Industry Milestone"

Newsroom Interview

Lee Dong-hoon, the youngest executive at SK Hynix, expressed confidence that the world's tallest 321-layer 4D NAND being developed by SK Hynix "is expected to become a new milestone in the industry."

In an interview with the SK Hynix Newsroom on the 14th, Vice President Lee stated, "Our short-term goal is to complete development as quickly as possible, supply the product, and minimize risks."

Born in 1983, Vice President Lee was appointed as the youngest newly appointed executive in the 2024 executive personnel reshuffle conducted at the end of last year, and was selected as an executive of the newly established organization this year, the 'N-S Committee.' The N-S Committee was newly formed as a control tower for the NAND and solution businesses to strengthen business competitiveness.

Vice President Lee was selected as an SK Hynix scholarship student in 2006, completed his master's and doctoral courses, and joined the company in 2011. He served as the head of the technology strategy team during the development of 128-layer and 176-layer NAND, and from the development of the 238-layer NAND, he was in charge of PnR (Performance & Reliability), playing a key role throughout the entire 4D NAND development process.

From a long-term perspective, Vice President Lee emphasized the need to continue attempts that have not been tried before. He said, "The core of NAND development so far has been to maximize performance relative to cost. The emergence of 4D NAND following 2D and 3D NAND was for this reason," adding, "Since we are currently at the center of transformation, NAND must also innovate with multiple directions."

He also stressed the need to focus on the rapid increase in data due to the expansion of artificial intelligence (AI) applications. Vice President Lee said, "Even in the automotive sector alone, data such as roads and traffic volume for autonomous driving is exploding," and added, "Since the performance and conditions required for NAND can vary greatly depending on the devices or environments generating data, we will closely monitor environmental changes and lead innovation to maintain technological leadership."

Vice President Lee predicted that NAND, following DRAM, will also turn upward this year. He mentioned, "The memory semiconductor market is riding an upward trend this year," and added, "Especially with the next-generation NAND product launch expected this year, we will strive to achieve better results during this period of transformation."
