Samsung Electronics' latest financial filing signals a significant shift in the electronics market, driven by the AI boom. For the first time, the company's DX division, responsible for smartphones and home appliances, has listed mobile memory as a key raw material purchase, indicating that the memory semiconductor super-cycle is now directly inflating the production costs of finished goods.
The core reason for this change is a major reallocation of resources within the semiconductor industry. First, the explosive growth in AI has created unprecedented demand for HBM (High Bandwidth Memory), which is essential for training and running AI models. Memory manufacturers, including Samsung's own semiconductor (DS) division, SK hynix, and Micron, have shifted their production focus from conventional mobile memory like LPDDR to the more profitable HBM to meet this demand. This strategic pivot was confirmed by reports of SK hynix's 2026 HBM supply being sold out as early as late 2025.
Consequently, this shift has created a supply shortage for the mobile memory used in smartphones and PCs. With less production capacity allocated to it, the supply of mobile DRAM tightened significantly. Market analysis from firms like TrendForce consistently pointed to this trend, forecasting dramatic quarterly price increases throughout late 2025 and early 2026. For instance, contract prices for some mobile DRAM were projected to jump by over 70-80% in a single quarter.
This brings us to the final link in the chain: the impact on production costs. The severe supply-demand imbalance has led to a steep rise in mobile memory prices. Samsung's filing quantified this impact, stating that prices had risen about 107% compared to the previous year's average. This cost pressure became so substantial that the DX division, which previously focused on components like processors and display panels, now has to manage and disclose mobile memory as a major cost item. This development makes the internal cost dynamics visible, showing how the success of the AI-focused DS division is creating a direct financial challenge for the consumer-facing DX division.
- DX (Device eXperience) Division: The division at Samsung Electronics responsible for consumer products, including smartphones (Galaxy series), TVs, and home appliances.
- HBM (High Bandwidth Memory): A high-performance type of memory used in graphics cards and AI accelerators. It offers much faster data transfer speeds than conventional memory, making it crucial for data-intensive AI computations.
- BOM (Bill of Materials): A comprehensive list of all the raw materials, components, and assemblies required to manufacture a product. A rise in the cost of items on the BOM directly increases production costs.
