Leo CXL Memory Connectivity Platform
E-Series, P-Series, A-Series
Astera Labs delivers Leo CXL™ Memory Connectivity Platform to eliminate memory bandwidth bottlenecks and capacity constraints for compute-intensive workloads such as AI and ML.
Description
Astera Labs’ Leo Memory Connectivity Platform for CXL 1.1 and 2.0 is the industry’s leading purpose-built SoC and hardware solution to eliminate memory bandwidth and capacity bottlenecks and reduce stranded memory in cloud servers.Leo CXL Smart Memory Controllers enable robust memory expansion and disaggregated memory pooling and sharing for processors, workload accelerators, and smart I/O devices. Leo eliminates the need to overprovision memory thereby reducing overall TCO and optimizing CPU efficiency and application performance for computational workloads.
Aurora A-Series CXL Smart Memory Hardware Solutions offer all the benefits of Leo Controllers and enable quick plug-and-play CXL deployment with faster time-tomarket for system OEMs and data centers.
