Rebellions and CoAsia SEMI to co-develop next-gen AI chiplets based on Rebel

Rebellions has partnered with system semiconductor design company CoAsia SEMI to jointly develop AI chiplets and software solutions for data centers.

The two companies held a signing ceremony for a development and supply agreement for AI chiplets based on Rebellions’ next-generation AI semiconductor, Rebel. The ceremony was attended by the CEOs of both companies, as well as Hee-Jun Lee, Chairman of the CoAsia Group.

Rebellions and CoAsia SEMI began their collaboration in April when they jointly secured a national R&D project for developing multi-petaflops-class Process-in-Memory (PIM) server semiconductor chiplets.

This joint development targets commercialization of products for data centers. It integrates CoAsia SEMI’s 2.5D silicon interposer and advanced packaging analysis, development, and manufacturing technologies.

Compared to traditional single SoC (System on Chip) architectures, the chiplet technology offers superior design flexibility, yield, power efficiency, and performance optimization—making it a key technology for AI servers in data centers and high-performance computing (HPC) environments.

The two companies stated, “We aim to complete product development and validation by the end of 2026 and begin large-scale mass production for domestic and global AI data centers.”

Rebellions also plans to commercialize its enhanced-performance AI semiconductor, ATOM MAX, within this year. In the second half of the year, the company will unveil a new product called Rebel Quad, which features a chiplet architecture and next-generation high-bandwidth memory (HBM3E).

Sung-Hyun Park, CEO of Rebellions, stated: “This collaboration is part of Rebellions’ AI semiconductor product diversification strategy. Together with CoAsia SEMI, we will build an advanced packaging ecosystem.”

DS Shin (Dong-Soo Shin), CEO of CoAsia SEMI and Head of the Semiconductor Division at CoAsia Group, added: “The technical cooperation between our companies will play a pivotal role in the AI semiconductor ecosystem. We are committed to maintaining a technological edge in the rapidly growing AI semiconductor market.”
