Micron Technology has reported that the demands of artificial intelligence (AI) are outpacing the capabilities of High Bandwidth Memory (HBM), with compute performance outstripping HBM bandwidth by three times every two years. This widening gap contributes to what is being referred to as the “memory wall,” which is increasingly impacting the performance of AI systems.
As AI large language models (LLMs) such as Meta’s Llama 3 evolve, the need for advanced memory technologies is becoming critical. Micron highlighted that failures in HBM were responsible for 17% of training interruptions for Llama 3, underscoring the urgent need for further innovation in memory solutions to meet the growing demands of AI.
Currently, HBM is the dominant DRAM type utilized in leading AI accelerators. However, as the performance of AI systems continues to improve, the limitations of existing memory solutions pose a significant challenge. Micron emphasizes the importance of advanced packaging and process technologies to address thermal constraints and enhance memory performance, which are essential to sustain the evolution of AI technologies.
