Rising Memory Demands in Automotive Sector Spark Supply Chain Crisis
A surge in demand for high-bandwidth memory (HBM) and server-grade chips driven by AI infrastructure projects has triggered a global memory shortage, disrupting automotive and consumer electronics manufacturing. The crisis, exacerbated by semiconductor manufacturers prioritizing high-margin server chips over commodity memory, has led to a 70% to 100% year-on-year price increase for legacy automotive memory, forcing automakers to confront escalating costs.
AI-Driven Demand Shifts Semiconductor Production
Global cloud providers and tech giants are securing AI accelerators, prompting memory makers to reallocate wafer capacity to high-margin server lines. “Demand will exceed supply in both 2027 and 2028, making market conditions significantly tighter than in 2026,” stated Micron CEO Sanjay Mehrotra.
Automotive Memory Requirements Soar
The automotive sector faces unprecedented pressure as vehicles evolve into “computers on wheels.” The Korea Automobile Research Institute (KARI) projects that average memory installed per vehicle will jump from 90 gigabytes (GB) in 2024 to 278GB by 2026, reaching 4 terabytes (TB) by 2030. Robotaxis, equipped with advanced self-driving systems, require over 200GB of DRAM—20 to 30 times more than conventional cars.
Concentration of Supply Chain Power
A triopoly of chipmakers—Micron, Samsung Electronics, and SK Hynix—controls roughly 90% of global automotive DRAM production, according to S&P Global Mobility. This oligopolistic structure has intensified bottlenecks, with legacy memory prices soaring as manufacturers prioritize HBM and server shipments. Small and mid-sized appliance makers, lacking the purchasing power of industry giants, now grapple with parts shortages and factory disruptions.
Manufacturers Seek Workarounds
In response, companies like Hyundai Motor Group are developing custom systems-on-chips (SoCs) to reduce reliance on imported semiconductors. Meanwhile, home appliance makers are optimizing AI algorithms to compress data and offset rising component costs. However, analysts warn that without long-term industry collaboration, the gap with foreign competitors could widen permanently.
Analysts Warn of Prolonged Supply Bottlenecks
Global investment banks, including Morgan Stanley and JPMorgan, predict the memory deficit will persist through 2028. Samsung Securities analyst Lim Eun-young noted, “Price increases are now spilling over into commodity memory, power semiconductors, and automotive chips.” The semiconductor shortfall is already disrupting broader manufacturing supply chains, echoing the 2021 chip crisis.
Future Outlook: A Race Against Time
With vehicle and appliance replacement cycles averaging seven to 10 years, manufacturers face limited opportunities to adapt. “Unless automakers, parts suppliers, and semiconductor firms establish long-term cooperative frameworks, the ecosystem gap with foreign competitors could widen permanently during the mobility AI transition,” cautioned KARI researcher Chang Hong-chang.
