0131 GMT - AI-driven memory demand is expected to remain strong through 2027 despite concerns that future AI systems may use less high-bandwidth memory, according to Mizuho Securities. The brokerage says aggregate DRAM demand continues to rise while supply remains tight, suggesting that worries about lower memory content in future AI accelerators may be overstated. Reduced memory requirements per chip could instead enable higher GPU and AI chip shipments, supporting broader AI deployment. Mizuho also expects global wafer fabrication-equipment spending to grow more than 25% in 2027, driven by new semiconductor fabs and continued AI investment. Uncertainty around the adoption of 800-volt power architectures in AI data centers could delay related infrastructure upgrades and equipment demand, it adds.
