How AI Is Supercharging Memory Demand

The report details how AI is revitalizing the memory market by creating a 'memory wall' that necessitates advanced, high-bandwidth solutions like HBM. This shift is driving higher profitability for vendors but resulting in tight capacity for traditional DRAM.

Key Takeaways

• 1.Memory bandwidth has become the primary bottleneck for AI performance as compute scaling outpaces data delivery, creating a 600:1 performance gap.
• 2.High-Bandwidth Memory (HBM) is shifting from a niche product to a high-margin strategic priority, with gross margins estimated at 55% to 65%.
• 3.The HBM4 transition in 2026 will mark a major architectural shift, moving the memory controller to a logic base die and doubling I/O channels to 2,048 bits.
