Meet MEXT

MEXT Predictive Memory™ is a software-only solution that makes flash appear as DRAM to the operating system. The result is a new price-performance tier that delivers DRAM-class performance at flash-level costs and capacity. Here's how it works.

The Challenge

Memory Is Expensive But Underutilized

For modern workloads, performance is increasingly constrained not by CPU speeds, but by DRAM capacity. On top of that, DRAM is one of the most expensive computing resources. For such a costly resource, the expectation would be that it would be well-utilized. In many environments, however, that is not the case. Studies from major cloud providers have shown that utilization often drops to 50% or lower—over half of the memory can be considered cold. This means that organizations are deploying much larger DRAM footprints than they truly need—resulting in potentially millions of dollars in wasted spend.

60-90% of System Cost

DRAM now accounts for approximately 60-90% of the cost of an individual server.

Over $100B Annual Spend

Global DRAM spend is over $100B and that number is rapidly expanding.

Often Less than 50% Utilization

DRAM utilization regularly drops to 50% or below across many business environments.

The Breakthrough

AI-Powered Predictive Memory™

MEXT is tackling the memory utilization problem with an unprecedented approach: transparent, AI-powered memory tiering. MEXT begins by offloading cold memory pages from DRAM to a 50X lower-cost tier, flash. The MEXT Predictive Memory™ Engine leverages the power of AI to continually predict which memory pages in flash are likely to be requested by the application, and transparently moves them back to DRAM—before the application even requests them. From the application's perspective, all relevant memory pages are always findable in DRAM, maintaining performance.

The Value

More Memory, Lower Costs

Through this AI-powered prediction, MEXT can keep application performance intact within a much smaller DRAM footprint—yielding substantially lower costs. Alternatively, MEXT can instantly enable 2-4X memory capacity on existing systems (through flash-as-memory), yielding superior performance for memory-bound workloads.
