Samsung Focuses on Redesigning 1c DRAM Process for Enhanced Yield Rates and Future HBM4 Development

Samsung is reportedly embarking on a redesign of its sixth-generation 1c DRAM with the aim of enhancing yield rates and establishing a competitive advantage in its forthcoming HBM4 process.

Revamping 1c DRAM: A Strategic Move for Samsung’s HBM4 Success

The South Korean technology leader is currently evaluating its 1c DRAM process design, integral to the anticipated success of the HBM4 process. Recent insights from ZDNet Korea reveal that since the second half of 2024, Samsung has been reimagining its advanced DRAM technologies. The redesign aims to facilitate smoother market integration for its upcoming memory solutions, particularly in light of the adoption challenges faced by HBM3 derivatives, which encountered significant hurdles with companies including NVIDIA.

The redesign efforts stem from concerns regarding yield rates associated with Samsung’s cutting-edge DRAM process, which have fallen short of anticipated targets. These yield rates are estimated to hover around 60%-70%, hindering the company’s transition to mass production. The principal challenge lies in the dimensions of the 1c DRAM chip. Despite the initial objective to downsize the chip for enhanced production volume, Samsung’s focus inadvertently affected process stability, leading to diminished yield rates.

Samsung Electronics has changed the design of its 1c DRAM to increase its chip size and is focusing on improving yields, targeting the middle of this year. It appears that they are focused on stable mass production of next-generation memory even if it costs more.

The efficacy of Samsung’s 1c DRAM process is key to the quality and success of its upcoming HBM4 products. Given the company’s less-than-stellar reputation following complications with HBM3, it is essential for Samsung to align its 1c DRAM outcomes with established industry standards.

While uncertainty lingers regarding the final results of Samsung’s 6th-generation DRAM efforts, projections suggest that advancements may emerge in the coming months. If successful, these developments could pave the way for Samsung’s HBM4 to enter mass production by the close of this year.
