Memory bottlenecks drive HBM shift to 8-layer stacks

DIGITIMESOctober 14, 2026en

As the gap between memory supply and demand widens due to the surge in AI applications, supply chain sources report that major GPU and custom ASIC vendors are considering lower-spec high-bandwidth memory (HBM) configurations for their next-generation architectures. Severely constrained supply is expected to drive a pivot toward 8-layer HBM in the second half of 2027. This move will not only boost memory makers' yields but, more importantly, enable a higher volume of finished systems to ship smoothly.
