SUNMMIO Raises New Funding for Stacked AI Inference Chips

THE ESSENTIALS

Nearly RMB2 billion refers to funding over the past year, not the disclosed size of one new round.

Funding for inference hardware

TechNode reported on October 14, citing EE Times China, that SUNMMIO completed Pre-A2 and Series A rounds led by Beijing state-backed investment platforms. The report puts its cumulative fundraising over the past year at nearly RMB2 billion.

From design to production

SUNMMIO plans to expand research staff and accelerate production of its 3D TokenPU processors. The report says its first A4E chip reached tape-out in June. Its stacked-memory design targets data movement in model inference; tape-out alone does not establish production scale or customer deployment.
