HBM4 cycle faces squeeze as capacity, specs become critical
What happened
According to an analysis of the South Korean supply chain, AI chipmakers' rising memory performance requirements are accelerating the shift from sixth-generation high-bandwidth memory (HBM4) to HBM4E. Major AI semiconductor customers are already pushing HBM4E development, which could potentially shorten HBM4's mass-production cycle, while suppliers' development and manufacturing capabilities, thermal management, and customer validation remain decisive. The source does not quantify any price or capacity impact of this trend.
