Data compiled by Woofun AI shows that US memory concept stocks experienced a collective slump in pre-market trading, heavily influenced by a plunge in South Korean memory equities. This regional downturn triggered a broad-based sell-off across the US sector, with SanDisk and Micron Technology leading the losses by falling over 9 percent.

Concurrently, other major players in the memory space faced significant pressure. Western Digital and Silicon Motion Technology retreated more than 8 percent, while Seagate Technology dropped over 7 percent. Rambus also saw a decline of more than 6 percent, underscoring the widespread impact of the negative sentiment on the global memory market.
