Overview: When it comes to generative AI, disruption is not just inevitable, it is the engine of progress. Amid this dramatic shift, memory solutions are racing to catch up, spurred by the demand for enhanced bandwidth, capacity, area efficiency, power management, heat dissipation, and cost-effectiveness. But there is no one-size-fits-all here, and the answer is custom memory, a space set to expand significantly by 2026 when HBM4 is poised to debut. Currently, seven to eight major IT players such as NVIDIA, Amazon, Microsoft, Broadcom, and Marvell are driving custom HBMs.
