SK hynix Launches Mobile DRAM with 3.5x Enhanced Thermal Conductivity to Address Performance Throttling for On-Device AI and Beyond

Advancements in Mobile DRAM Technology for Enhanced Smartphone Performance

As the demand for on-device AI applications grows, smartphone DRAM and memory manufacturers are actively developing faster and more efficient chips to enhance performance and mitigate issues associated with current technologies. Leading the charge is We hynix, which has recently outpaced Samsung in various aspects of memory technology. The company has introduced an innovative mobile DRAM that features a groundbreaking ‘Molding Compound’ aimed at combating the overheating challenges faced by modern smartphones. Remarkably, We hynix claims that this new memory chip boasts a thermal conductivity improvement of 350%.

Technological Innovations to Combat Overheating

In certain device architectures, mobile DRAM is mounted directly atop the chipset die, leading to significant challenges during high-performance tasks. Excessive heat generated in these circumstances can result in throttled performance, a concern that most smartphone manufacturers encounter. This design choice, however, is popular because it maximizes space efficiency and accelerates data transfer between the DRAM and the chipset due to reduced travel distance for the data.

Industry Insights from We hynix

Lee Gyu-jei, the head of Package Product Development at We hynix, describes the utilization of the High-K Epoxy Molding Compound as a significant milestone. According to Gyu-jei, this innovative solution not only enhances performance but also alleviates various issues faced by users of flagship smartphones.

“It’s a meaningful achievement that goes beyond a simple performance improvement as it addresses the inconvenience that many high-performance smartphone users may have had. We are committed to firmly establishing our technological leadership in the next-generation mobile DRAM market with our technological innovation in materials.”

Future Prospects for Mobile DRAM

By incorporating advanced compounds into the traditional Epoxy Molding Compound, We hynix has significantly enhanced thermal management capabilities. Although a specific timeline for the rollout of these advanced mobile DRAM chips has not been disclosed, industry experts speculate that we could see this technology integrated into flagship smartphones by 2026.

This development underscores a broader trend in the semiconductor industry, where addressing thermal constraints is crucial for optimizing the performance of devices increasingly reliant on artificial intelligence and high-efficiency computing.
