Marvell Structera Transcends CXL Memory Expansion
Marvell’s Structera CXL chips boost memory bandwidth and capacity. Structera A, a DPU with 16 Neoverse-V2 cores, accelerates workloads, while Structera X expands memory capacity and supports dual-host pooling. Sampling now, both accelerate encryption and compression to add security and increase effective memory capacity.

Marvell Copackages Optics for Custom Silicon
Marvell’s custom silicon operation now offers copackaged optics (CPO). Enabling systems to connect fiber-optic networks directly to chips such as AI accelerators (NPUs) and network switches raises per-chip bandwidth and extends interchip connectivity distances. Few companies offer CPO. Broadcom, Marvell’s main custom-silicon rival, has developed a few Ethernet switches implementing the technology and, this past…
