AI Breakthrough From Google Exposes Divide in Memory Chip Stocks

A two-day selloff in memory-chip stocks is revealing a new split in the artificial intelligence trade, as Google touts a breakthrough that analysts say may curb demand for certain types of storage while leaving others largely unscathed.

Shares of Samsung Electronics Co. and SK Hynix Inc. — makers of high-bandwidth memory used in Nvidia Corp. AI accelerators — erased most of their declines in Seoul on Friday. Their US-listed peer Micron Technology Inc. was also steady in pre-market trading. Meanwhile, losses extended for makers of flash memory including Japan’s Kioxia Holdings Corp. that had soared in recent months.
