en.Wedoany.com Reported - AMD announced on Monday the acquisition of startup MEXT. MEXT has developed memory tiering technology that allows operating systems to recognize NAND flash memory as DRAM, helping data center operators reduce DRAM costs. AMD stated that this deal will help customers improve system efficiency, lower operational costs, and deploy large-scale workloads more quickly.
As AI models scale up and datasets grow, memory availability is becoming a critical constraint on overall system performance. In many scenarios, memory resources—rather than CPUs or GPUs—have become the performance bottleneck, while DRAM utilization often remains low. MEXT addresses this efficiency challenge with AI-based memory tiering technology: it migrates infrequently accessed data from expensive DRAM to NAND flash memory, which costs orders of magnitude less per unit capacity, all transparently to applications. The company's predictive memory engine continuously analyzes memory access patterns, using AI models to anticipate which data stored in flash will be needed next, and proactively moves the corresponding pages back to DRAM before the application requests them, allowing software to operate as if accessing main memory, thereby maintaining performance levels.
By increasing the total amount of memory available to applications, MEXT's technology aims to improve utilization of existing infrastructure while reducing reliance on expensive DRAM. This approach is expected to lower the total cost of ownership for cloud service providers and enterprise customers, enabling larger workloads to run on existing hardware. AMD believes these capabilities are applicable to both traditional data center scenarios and modern AI deployments—where access to large memory pools is critical for efficiency and scalability. AMD plans to integrate MEXT's technology into its own data center products and expand its capabilities to address memory-intensive AI workloads. The company already offers solutions integrating processors, accelerators, networking technologies, and software, and MEXT's predictive memory engine will complement its existing product lineup.
Beyond the technology itself, AMD also gains a team with expertise in memory architecture, infrastructure software, and large-scale computing systems. The terms of the deal were not disclosed.
