The memory chip sector rallied in after-hours trading, driven by reports of a massive surge in DRAM export prices, which are up 401% year-over-year. This highlights the sector's significant pricing power amid soaring demand from AI data centers. Adding to the bullish sentiment, Samsung announced a new processing-in-memory (PIM) chip at the Hot Chips conference, which significantly accelerates AI processing by performing computations directly within the memory, boosting AI response speeds by more than three times.
