Samsung Completes Development of Next-Generation HBM4 Memory
Samsung has reached a significant milestone in memory technology, completing the development of its first sixth-generation High Bandwidth Memory (HBM4) chips. According to reports from AjuNews and Korean industry insiders, Samsung’s Device Solutions division has achieved Production Readiness Approval (PRA), the final internal step before initiating large-scale manufacturing. This advancement positions Samsung at the forefront of the high-performance memory market, particularly as demand for advanced AI and data center solutions continues to surge.
HBM4: A Major Leap in Memory Bandwidth
The new HBM4 chips are expected to deliver approximately 60% higher bandwidth compared to the current HBM3E generation. This substantial increase is set to meet the growing requirements of next-generation GPUs and AI accelerators. Samsung has already shipped HBM4 samples to NVIDIA, which is currently evaluating the chips for integration into its upcoming Rubin platform. Early testing indicates that these samples have surpassed NVIDIA’s next-generation GPU requirement of 11 Gbps per pin, highlighting the performance potential of Samsung’s latest memory technology.
Advanced Technology for Enhanced Performance and Efficiency
Samsung’s HBM4 leverages improved 1c-class DRAM combined with a 4 nm logic base die. This advanced architecture not only boosts performance but also helps manage thermal output and power consumption, critical factors at higher data rates. The combination of cutting-edge DRAM and logic technology enables Samsung to close the gap with competitors while maintaining efficiency and reliability.
Path to Mass Production and Future Developments
With production lines already prepared, Samsung is poised to begin volume manufacturing as soon as NVIDIA completes its evaluation and provides approval. During its Q3 2025 earnings call, Samsung confirmed that HBM4 samples had been distributed to global customers, with mass production scheduled for 2026. The company also emphasized that its foundry division will focus on stable 2 nm Gate-All-Around (GAA) process output and HBM4 base-die production, coinciding with the ramp-up of its new Taylor, Texas fabrication facility.
Looking ahead, Samsung is reportedly developing an even faster HBM4 variant, targeting an additional 40% performance increase. Industry sources suggest that an official announcement regarding this enhanced version could arrive as early as mid-February 2026, further solidifying Samsung’s leadership in high-performance memory solutions.
