No eternal allies. No perpetual enemies. The old proverb seems so true when it comes to the semiconductor industry, when the world’s top foundry, TSMC, announced the collaboration with its rival Samsung, the second largest foundry globally, on the development of HBM4, according to the reports by Korean media outlets the Korea Economic Daily and Business Korea. According to analysts cited by the Korea Economic Daily, it would mark their first partnership in the AI chip sector.

Citing the remarks of Lee Jung-bae, Head of the Memory Business Division at Samsung Electronics at SEMICON Taiwan, the reports note that in order to advance in HBM, Samsung is preparing over 20 customized solutions in collaboration with various foundry partners. However, Lee declined to comment on which specific foundry they were partnering with.

The answer has been revealed when on September 5^th, Dan Kochpatcharin, Head of Ecosystem and Alliance Management at TSMC, confirmed that the two companies are working together on developing a buffer-less HBM4 chip.

According to Business Korea, buffer-less HBM is a product that eliminates the buffer used to prevent electrical issues and manage voltage distribution, which Samsung targets to introduce with HBM4. The innovation is expected to enhance power efficiency by 40% and reduce latency by 10% compared to existing models.

The reports note that the main consideration Samsung chooses to team up with TSMC would be the attempt to incorporate customized features requested by major clients like NVIDIA and Google.

Although Samsung can offer a full range of HBM4 services, including memory production, foundry, and advanced packaging, the company aims to utilize TSMC’s technology to attract more clients, according to sources cited by the reports.

The manufacturing process for HBM4 differs from previous generations, with the logic die, the component that functions as the brain of an HBM chip, may now be produced by foundry companies rather than memory manufacturers.

Earlier in April, SK hynix, the current HBM leader as well as Samsung’s biggest rival on memory, announced the partnership with TSMC on HBM4 development and next-generation packaging technology.

Though months later than SK hynix and Micron, Samsung’s 8-layer HBM3e has reportedly started shipments to NVIDIA. It targets to gain a competitive edge with its rival in HBM4, eyeing to enter mass production by late 2025.
