Samsung has moved ahead of Micron in the automotive memory market, and the numbers are big enough to make the shift hard to ignore. New data from S&P Global Mobility puts Samsung Electronics at 40% of the worldwide automotive memory market as of 2025, up 5 points from 2024, while Micron slipped from 40% to 35% over the same period.
That matters because automotive memory is no side hustle anymore. Modern cars are packed with connected systems, infotainment, driver-assistance hardware, and storage-hungry software, so the supplier that gets designed in early often keeps the business for years. Samsung already has scale in NAND, DRAM, and HBM, and this latest lead shows it is turning that chip muscle into a deeper position inside vehicles too.
Samsung’s expanding automotive memory lineup
The company’s automotive portfolio is broader than a single memory type. Samsung says its range now includes LPDDR, UFS, automotive solid-state drives, and GDDR memory, which gives it more ways to sell into vehicles with different compute and storage needs. It has also been shipping memory solutions to automakers since 2015, so this is less a sudden breakout than a long campaign finally showing up in the market share table.
One of the clearest signs of that push is China, where Samsung has been shipping more memory solutions to automakers as it expands its customer base. That is a sensible place to fight for volume: the market is huge, competition is fierce, and whoever wins platform designs there can build meaningful scale fast. Micron is still very much in the game, but losing a tie at the top is not the kind of statistic a supplier frames in a cheerful slide deck.
Automotive memory market share in 2025
Samsung’s gain also fits a bigger pattern in semiconductors. The company has been strengthening its memory position across categories, and automotive is now another place where that breadth pays off. For carmakers, the appeal is obvious: fewer suppliers, more product coverage, and a vendor that can keep up as vehicles become more software-defined and more memory-intensive.
- Samsung share in the worldwide automotive memory market in 2025: 40%
- Samsung share in 2024: 35%
- Micron share in 2024: 40%
- Micron share in 2025: 35%
- Samsung has shipped memory solutions to automakers since 2015
The open question is whether Samsung can keep widening the gap as carmakers juggle cost pressure, regional sourcing, and the next wave of in-vehicle computing. If the company keeps converting its broader memory leadership into automotive wins, Micron may find that getting back to the top is harder than getting there in the first place.
