Intel patent reveals XBM memory architecture as HBM alternative for AI

Intel's XBM patent proposes a new memory architecture that replaces HBM's costly silicon interposer with backend-transistor DRAM stacks. The design uses UCIe chiplet links and built-in repair logic to reduce packaging costs and complexity for AI workloads.
