Samsung Electronics Chief Technology Officer Song Jai-hyuk said Wednesday the company’s high-bandwidth memory 4 (HBM4) chip is showing “good” manufacturing yield, adding that clients have expressed strong satisfaction with its performance.
“We may have fallen short of demonstrating our world-class technological responsiveness to customer needs for a while, but this should be seen as a return to that standard,” Song told reporters before his keynote speech for SEMICON Korea 2026 in Seoul.
Samsung reportedly plans to begin HBM4 mass production and shipping to major customers later this month. Its HBM4 chips are using its 1c process, the sixth-generation 10-nanometer-class DRAM technology, for the DRAM cell die, while using a 4-nanometer foundry process for the base die.
Based on these technologies, Samsung had its HBM4 chips achieve data processing speeds of up to 11.7 gigabits per second (Gbps), exceeding the Joint Electron Device Engineering Council’s standard of 8 Gbps.
Since they are the industry’s latest technologies, questions have been raised over how the company will secure production yield as operations ramp up, but Song expressed confidence.
“It is difficult to describe (the yield) in numbers, but I can say the status is very good,” he said, adding that customers are “very satisfied” with the performance of the chip.
“In terms of technology, we believe we remain at the top. The question of how we manage our portfolio falls into the realm of business … We believe our in-house capabilities spanning memory, foundry and packaging create the best environment for making artificial intelligence (AI)-driven products, and the combination is generating synergy.”

During his keynote speech, Song stressed Samsung Electronics’ advantage as a company capable of foundry, memory and chip packaging businesses, saying it will demonstrate a “distinctive and powerful Samsung-only semiconductor synergy through co-optimization.”
