Samsung HBM4E yield tops 70%, intensifying AI memory competition

Samsung has achieved a yield rate exceeding 70% for its HBM4E memory chips. This indicates that over 70% of the HBM4E chips produced are functional and meet quality standards. This improvement in manufacturing efficiency is a key development for Samsung in the high-bandwidth memory sector.

This matters because HBM4E memory is critical for advanced Artificial Intelligence (AI) applications, particularly for powering high-performance Graphics Processing Units (GPUs). Higher yields allow Samsung to produce more chips cost-effectively, which is essential for meeting the growing demand from AI chip developers.

The mechanism involves Samsung optimizing its manufacturing processes for HBM4E, which is the next generation of high-bandwidth memory. By refining fabrication steps and reducing defects, the company can produce a greater number of usable chips from each silicon wafer, thereby increasing overall output and reducing per-unit costs.

This development intensifies competition in the AI memory market, primarily impacting Samsung (005930.KS) by strengthening its supply capabilities. It also puts pressure on rivals like SK Hynix (000660.KS) and Micron Technology (MU) as they vie for market share and contracts with major AI chip customers.
