SK Hynix is trading 7.26% down now at €1085 after investors reacted to DeepSeek’s V4.1-Flash architecture, which uses one-quarter the HBM and one-eighth the SSD storage for its key-value cache versus the prior generation.
- DeepSeek began routing V4-Pro requests to the lower-cost Flash model on September 14.
- The move intensified concerns about future high-bandwidth-memory demand, while Frankfurt-listed shares followed the broader memory-chip sector lower.
