Samsung Reportedly Revamping 1c DRAM Process to Enhance Yield Rates and Influence HBM4 Development

Samsung is reportedly setting its sights on overhauling its 6th-generation 1c DRAM as it works to enhance yield rates and secure a competitive edge for its anticipated HBM4 process.

### The Significance of Samsung’s 1c DRAM in Its HBM4 Venture and Overall Memory Business Success

The tech giant from Korea is contemplating a revamp of its 1c DRAM process, a crucial component for the successful rollout of its HBM4 technology. According to a report by ZDNet Korea, since the second half of 2024, Samsung has been scrutinizing its advanced DRAM design. It has now decided on a new design for its high-end 1c DRAM to avoid the challenges faced by previous iterations, like the HBM3 versions, which struggled with adoption by companies such as NVIDIA.

The report reveals that Samsung’s state-of-the-art DRAM technology did not meet its targeted yield rates, which were projected to be between 60% and 70%. As a result, the company has been unable to move into mass production stages. The primary issue seems to be tied to the size of the 1c DRAM chip; Samsung initially aimed to shrink the chip size to boost production volumes. However, this size reduction inadvertently compromised the process’s stability, leading to decreased yield rates.

The importance of Samsung’s 1c DRAM in shaping the future of its HBM4 offerings cannot be overstated. As competitors like SK Hynix and Micron advance their own designs, time is ticking for Samsung. The company, which is still reeling from the fallout of its HBM3 debacle, knows all too well the importance of getting its 1c DRAM process right to meet industry standards.

Currently, the outlook for Samsung’s 6th-generation DRAM process remains uncertain. However, developments expected in the coming months might set Samsung’s HBM4 process back on course for mass production by year-end. This could potentially mark a turning point for the company’s endeavors in the memory industry.
