Hybrid 2.5D and 3D Packaging Points to Denser AI Memory Architectures

The article explains how AI and HPC chip designs are moving beyond simple planar layouts toward architectures that mix interposer-based integration with stacked-die techniques. The memory angle is the role of high-bandwidth memory beside logic and accelerators in advanced packages. For RamTrend, this is an architecture signal: more complex packaging can improve bandwidth and system density for AI accelerators, but it also raises manufacturing, thermal, and cost tradeoffs that may affect future HBM platform design rather than near-term memory prices.
