According to reports, with data centers stepping up their expansion efforts and the cloud - computing sector making a transition from AI training to AI inference, there has been a significant surge in the demand for large - capacity memory. This has, in turn, fueled a recovery in the global NAND flash memory market. Insider sources disclosed that Samsung Electronics has ramped up operations at its primary NAND factory located on the Pyeongtaek campus. In the third quarter of 2025, the capacity utilization rate of its eighth - generation (V8) NAND production line witnessed an increase of over 10% compared to the previous quarter, soaring to approximately 80%. Here, “stepping up...efforts” is a more natural English expression compared to the original “accelerate their expansion”, which conveys a sense of actively and vigorously increasing the scale of expansion. “Making a transition from...to...” is a common and clear way to describe a change from one state to another, replacing “shifts from...to...”. “Insider sources” is a more specific and commonly used term in news reporting than just “sources”. “Witnessed an increase” is a more vivid and idiomatic way to express the change in the utilization rate, and “soaring to” emphasizes the significant rise, making the description more dynamic.
