AI fabless company DifferAI announced on the 28th that its self-developed edge AI semiconductor chip ‘Tachy-BS402’, which recently began mass production, is receiving great attention from the industry due to its ‘chip-to-chip communication’ technology.


Chip-to-chip communication is a next-generation technology for combining multiple semiconductor modules into one. Recently, as high-performance chips are required in the process of building AI servers, chip-to-chip communication technology has been gaining significant attention. Global semiconductor companies are also actively adopting this technology to improve efficiency.


Representative examples of chip-to-chip communication technology include Apple’s ‘UltraFusion’, AMD’s ‘Chiplet’, and NVIDIA’s ‘NV Link’.


DifferAI applied its domestically first self-developed chip-to-chip communication technology ‘X2X’ to the Tachy-BS402. Through this, the Tachy-BS402 successfully achieved resource efficiency by effectively distributing loads while delivering high performance with low power consumption.


Unlike typical NPU (Neural Processing Unit) developers who focus solely on raising performance indicators such as ‘TOPs (Tera Operations Per Second)’, DifferAI actively adopts advanced technologies like chip-to-chip communication. The company explained that it plans to structurally enhance product performance to target the global market.


A DifferAI representative said, “Chip-to-chip communication technology is currently the most notable technology in the semiconductor market,” adding, “The Tachy-BS402, which applies X2X technology, can replace GPU (Graphics Processing Unit) and CPU (Central Processing Unit) chips, making it a product with very high added value.”



DifferAI conducted backend design and mass production through Aegisland, the only TSMC design house in Korea. They plan to build customized servers specialized for inference services using the Tachy-BS402. As advanced AI services such as generative AI emerge, the required resources are also increasing significantly. DifferAI’s semiconductor chip can provide an environment optimized for data utilization.
