Intel patents XBM memory architecture to cut AI chip costs

Intel has patented a new memory architecture called XBM (Cross-Batch Memory) designed to reduce the cost and complexity of AI memory systems. XBM aims to bypass the need for expensive silicon interposers used in High Bandwidth Memory (HBM) by employing backend-transistor DRAM and UCIe interconnects. This approach could alleviate the "memory wall" bottleneck in AI chips by offering improved scalability and built-in repair mechanisms to enhance yield. AI

IMPACT Could reduce AI chip manufacturing costs and improve memory performance.

RANK_REASON Patent application for a new memory architecture.
