Samsung Electronics Co Ltd has increased its HBM4 chip production yield to 80% [1], [2].
This surge in manufacturing efficiency allows the company to scale its high-bandwidth memory production to meet the escalating demand for artificial intelligence hardware. By stabilizing yields, Samsung positions itself to challenge competitors for dominance in the specialized memory market required for AI processors.
The company is now targeting an AI-memory market share of around 38% by the end of the year [1]. To reach this goal, Samsung plans to more than triple its HBM4 revenue during the third quarter [1]. This aggressive growth strategy is designed to capture a larger portion of the AI-memory sector as data centers expand their capacity.
Production is centered at the company's facilities in Seoul, South Korea [1]. The shift toward HBM4 is expected to redefine the company's product mix in the coming months. Samsung expects HBM4 to account for more than 60% of its total HBM sales during the second half of 2026 [1].
Industry analysts said the move puts increased pressure on other memory providers. The ability to produce high-yield HBM4 chips reduces waste and lowers the cost per unit, potentially allowing Samsung to offer more competitive pricing while maintaining margins. The company's focus remains on accelerating its comeback in the AI-memory space to secure long-term contracts with major chip designers.
“Samsung HBM4 production yield reaches 80%”
The jump to an 80% yield indicates that Samsung has overcome significant technical hurdles in the fabrication of next-generation high-bandwidth memory. Because HBM4 is critical for the performance of AI accelerators, Samsung's ability to mass-produce these chips reliably reduces the market's reliance on a single supplier and could trigger a pricing war in the AI-memory sector.
