Marvell shows photonic module that puts AI memory 50 meters from the GPU

The Photonic Fabric Memory Module uses light instead of copper to pool high-bandwidth memory far beyond the chip's edge For years, the fastest memory in an AI server has had to sit practically on top of the processor. Marvell Technology says it can now move that memory up to 50 meters away. The company’s Photonic Fabric Memory Module uses optical links to let high-bandwidth memory, both HBM and DDR, operate at that distance from a GPU or XPU. The usual electrical limit is 1.5 mm.
