Faced with continuously rising storage chip prices, Apple Inc. is undertaking a critical supply chain adjustment. According to supply chain sources, Apple plans to establish a partnership with Chinese domestic semiconductor company Yangtze Memory Technologies Co. (YMTC), integrating its NAND flash memory chips into iPhone product lines exclusively for the Chinese market.

Since the second half of last year, the global storage chip industry has entered a price increase cycle, severely squeezing Apple's profit margins. As reported by Wccftech, Apple was compelled to accept Samsung's proposed price hike contracts, with the procurement cost for a single LPDDR5X memory chip surging to $70.

YMTC's Technical Capabilities Recognized

Leveraging its self-developed Xtacking architecture, YMTC has achieved significant technological breakthroughs. According to TechInsights teardown analysis, the company has already mass-produced its fifth-generation 3D NAND flash memory chips, with a total stacking layer count reaching 294 layers—232 of which are active storage layers. The bit density approaches 19.8Gb per square millimeter, with area efficiency nearing the levels of leading global NAND manufacturers.

In terms of core performance metrics, YMTC's 300+ layer 3D NAND products can now directly compete with flagship offerings from the same generation by Samsung (286 layers) and SK Hynix (321 layers). This technical strength provides a solid foundation for Apple's evaluation of YMTC's entry into its supply chain.

Apple's Strategic Considerations

This move by Apple embodies dual strategic objectives. On one hand, introducing YMTC provides Apple with leverage in negotiations with Japanese and Korean storage giants, reducing excessive dependence on Samsung, SK Hynix, and Kioxia. On the other hand, limiting YMTC NAND to iPhone models sold exclusively in the Chinese market helps Apple secure cost advantages while circumventing potential geopolitical risks.

Notably, both YMTC and ChangXin Memory Technologies (CXMT) were briefly included on the U.S. Department of Defense's restricted entity list, but were subsequently removed—a series of developments that may be closely related to Apple's supply chain assessment.

Market Landscape and Impact

Should this cooperation materialize, it would mark a significant restoration of relations between Apple and YMTC since their collaboration was suspended in 2022 due to U.S. export controls. As a major participant in the global storage chip market, any adjustment to Apple's supply chain will trigger ripple effects. YMTC currently maintains a monthly production capacity of approximately 400,000 wafers, with its global market share potentially exceeding 12% after capacity expansion. A partnership with Apple would further consolidate its competitive position in the global NAND flash market.
