Apple is changing how it sources memory for future iPhones. Rising component prices and tight supply have pushed the company to rely more heavily on Samsung. You will see this shift most clearly in the iPhone 17 lineup, where Samsung is set to become the main memory supplier.
This change centers on low-power DRAM, known as LPDDR. Apple uses this memory because it saves power and controls heat in mobile devices. As memory prices climb, Apple now prioritizes suppliers that can deliver huge volumes with stable performance. That requirement narrows the field quickly.
According to The Korea Economic Daily, Samsung will supply about 60 to 70 percent of the LPDDR used in the iPhone 17. Earlier iPhone models relied on a more even split between Samsung and SK Hynix, with Micron taking a smaller share.
Apple is Shifting Orders
Memory supply has tightened across the industry. SK Hynix and Micron now focus much of their production on high-bandwidth memory for AI servers and data centers. That shift limits how much mobile-focused LPDDR they can deliver. Samsung, by contrast, continues large-scale production of general-purpose and mobile DRAM. Industry sources describe Samsung as the only supplier that can meet Apple’s demand for “extremely large and predictable volumes.”
Apple’s hardware also raises the bar. The company is highly sensitive to “product variation” and even brief voltage spikes. Its latest chips, including the A19 and A19 Pro, require memory that behaves the same across tens of millions of units. Samsung’s consistency plays a key role here.
Prices Rise, Stakes Increase
Costs add more pressure. A 12GB LPDDR5X module now sells for about $70, up from roughly $30 earlier this year. Apple usually shields itself with long-term contracts, but this jump changes the equation. Concentrating orders with Samsung helps secure supply and reduces risk, even as overall costs rise.
Looking ahead, Apple’s dependence on Samsung is likely to grow. AI features demand more memory, and the iPhone 17 models use 12GB LPDDR5X, the largest capacity Apple has ever shipped. As memory becomes central to on-device AI, supplier reliability matters more than ever.
