DreamBig Semiconductor, featured in this year’s edition of EE Times’ “Silicon 100” list of startups to watch for their chiplet technology, has been acquired by Arm. The revelation came buried in Arm’s latest earnings report, in which the British semiconductor IP supplier agreed to acquire DreamBig for $265 million in October 2025.

“The core technology centers on the MARS chiplet platform, which includes the Chiplet Hub technology with high-bandwidth memory DRAM,” the Silicon 100 report noted in DreamBig’s profile. The Chiplet Hub technology integrates 3D HBM on top of a high-performance fabric base die, providing designers with centralized control of shared hardware resources across attached chiplets.

Silicon 100 also mentioned the company’s high-performance accelerator solutions for AI and data centers. DreamBig’s network accelerator chip incorporates a remote direct memory access (RDMA) engine to support 800 Gbps of bandwidth and 800 Mpps of throughput for intensive AI workloads.

The above product outline leads to two semiconductor design offerings. First, its chiplets IP, called Chiplet Hub, enables developers to create multi-die architectures with quad-sided UCIe die-to-die connectivity. Case in point: Athos Silicon has incorporated Chiplet Hub technology in its inaugural chip, code-named Polaris, to develop a chiplet-based platform for automotive, avionics, robotics and space applications.
