Chip giant SK hynix has reported that its U.S. sales accounted for over 70 percent of its total revenue in the first quarter on rising demand for premium high bandwidth memory (HBM) chips from major U.S. tech companies.
During its first-quarter earnings call with analysts, Kim Jae-joon, executive vice president of Samsung’s memory business, said the company is already collaborating with multiple customers on custom versions based on both HBM4 and the enhanced HBM4E.
