Leading the Way

It is very difficult to consistently satisfy both individuals and the group. Our team leaders strive to create an inclusive culture where team members with various needs can freely express their opinions and share insight to move the team forward.


The Way I See It: Keith Jangryul Kim (Team Leader)

Tell us about DRAM Technical Marketing team at SK hynix: “As the head of the DRAM Technical Marketing team in SK hynix America, I’m responsible for covering all future DRAM applications, such as the DDRx, HBMx, LPDDRx, GDDRx and CXL solution. My team is great, and I really do believe that we are part of a bigger family. I think it’s important to show trust, consideration, and respect for family members, and this is exactly what I strive for within my team.”

How would you describe the company culture: “I would describe SK hynix America as a half-and-half combo chicken: one half is spicy seasoned chicken, and the other half is fried chicken. There is a mix of Korean and American culture and I try to take advantage of the two cultures. Diversity in ideas (and also food) is great, and I try to bring the best features into a good mix.”

What’s next for DRAM Technical Marketing at SK hynix: “Memory will be a key driver for the 4th industrial revolution, and SK hynix will need to focus on how our products would enable faster computations, transport, and storage of data. We really feel great when we see our ideas and tech innovations are enabled in the field, with increased customer satisfaction and expanded business opportunities.”
