Siyoung Choi, president of Samsung Electronics’ Device Solutions (DS) division, recently led a senior executive delegation to Silicon Valley, foregoing South Korea’s extended May holidays. The week-long trip focused on meetings with major US tech firms—including Apple, Nvidia, and Broadcom—to shore up demand across Samsung’s semiconductor portfolio, from DRAM and high-bandwidth memory (HBM) to foundry services. US tariff policy was also a key topic on the agenda.
