AMD Just Acquired MEXT to Crack the Memory Optimization Problem. Should Micron and Sandisk Investors Be Nervous?
Key takeaways
- According to MEXT's own press release, the software can cut memory costs by nearly half while expanding usable memory capacity by two to four times.
- In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia.
- For investors in Micron Technology (NASDAQ: MU) and Sandisk (NASDAQ: SNDK), the knee-jerk read is obvious: If AMD can teach flash to behave like DRAM, demand for high-bandwidth memory contracts declines.
Micah Zimmerman, The Motley Fool Mon, June 29, 2026 at 1:20 AM GMT+7 5 min read AMD MU SNDK NVDA About two weeks ago, Advanced Micro Devices announced the acquisition of MEXT, a start-up that has built artificial intelligence (AI)-driven software designed to make NAND flash behave like dynamic random-access memory (DRAM).
The technology uses predictive algorithms to identify frequently accessed data and move it between flash storage and high-speed memory in real time, reducing the amount of expensive DRAM a data center needs to run AI workloads at scale. According to MEXT's own press release, the software can cut memory costs by nearly half while expanding usable memory capacity by two to four times.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »
