Domestic Automotive‑grade Storage Enters Window for Large‑scale Vehicle Integration

According to China Securities Journal, iterative computing hardware for intelligent vehicles has driven a sharp rise in storage demand through 2026, while major global memory producers have redirected manufacturing capacity towards artificial intelligence products. Tight supply for automotive‑grade memory chips has become a prominent source of cost and supply‑chain risk for vehicle manufacturers. Domestic carmakers have locked in pricing through long‑term contracts and pursued in‑house chip development to offset external exposure, alongside accelerated validation and design‑in work for locally made storage components. Shifts forced by market balances are opening a critical phase for the mass roll‑out of domestic automotive storage.

Contract prices for standard DRAM rose by between 90 and 95 per cent quarter on quarter in the first three months of 2026, while NAND contract prices climbed by 55 to 60 per cent. Procurement costs for automotive storage increased by roughly 180 per cent between March and June. Shortages have delayed deliveries for multiple vehicle models, with supply constraints traced to the reallocation of advanced process capacity by Samsung, SK Hynix and Micron from the second half of 2025, prioritising high‑margin HBM and server DRAM for artificial intelligence deployments.

Restructuring of vehicle electrical and electronic architectures has lifted memory requirements substantially. Petrol‑powered vehicles generally operated with between two and four gigabytes of memory, whereas mainstream models with advanced driving systems and multi‑screen cabins carry 16 to 32 gigabytes. Flagship passenger vehicles now ship with 64 to 128 gigabytes, marking a structural jump in consumption rather than gradual expansion. Vehicle manufacturers have adopted decoupling strategies between chips and controllers, alongside internal chip programmes, to protect production volumes amid constrained component availability.

Micron signed long‑term supply deals in July with Qualcomm, Visteon, Harman, Denso and Hyundai Mobis, reserving its limited automotive output for established international tier‑one suppliers. Domestic storage vendors have accelerated customer qualification as local brands seek alternative supply lines. Biwin Storage has shipped automotive‑grade products to more than forty vehicle and component manufacturers. Longsys supplies automotive modules to over twenty original equipment makers and fifty tier‑one suppliers, with its self‑controller UFS devices undergoing testing for advanced driving platforms. Unigroup Guoxin has put automotive LPDDR into mass production, while GigaDevice and Xinyi Semiconductor maintain steady volume shipments of automotive NOR flash memory.

Co‑validation between domestic autonomous driving processors and local storage is shortening hardware and software integration cycles. Aixin Yuanzhi’s M57 chip for mid‑to‑high tier driving functions has secured design wins across several vehicle programmes, with integrated parking and forward vision solutions entering volume delivery. Its M97 chip for urban high‑level autonomous driving achieved silicon bring‑up in February, with leading carmakers running full evaluation sequences. Joint testing removes reliance on imported storage and creates opportunities for local suppliers to secure production orders.

Certification and inclusion on selection shortlists do not guarantee consistent mass supply. Integration into automotive supply chains follows extended evaluation cycles covering the complete service life of a vehicle. Long‑term performance on production models determines whether components remain qualified for purchase. Limited shipment volumes hinder unit cost reduction, while sustained order growth supports stable yield, factory utilisation and predictable pricing.

Industry assessments indicate tight supply for automotive memory will persist through 2026 and into the end of 2027. The window for domestic suppliers therefore stretches across at least two years. Small‑batch installation precedes large‑scale roll‑out, with new components required to complete three to four years of real‑world road testing before wider adoption. Wafer fabrication, yield management, packaging and testing, and controller development remain central bottlenecks. Many local storage chips rely heavily on overseas foundry capacity, leaving them exposed to external production limits.

Local vehicle groups face upward cost pressure from memory inflation, which speeds efforts to diversify their supply base. Domestic storage and autonomous chip developers gain from the capacity gap, though scaling depends on progress across reliability validation, yield improvement and cost reduction. Converting trial orders into sustained high‑volume deliveries will decide whether temporary market opportunity translates into lasting structural change within the sector.
