Samsung Electronics South Korea

Overview

Samsung Electronics has commenced shipments of industry-first 12-layer HBM4E samples to key global customers. This HBM4E improves energy efficiency by 16% and thermal resistance by over 14% compared to HBM4, while delivering memory bandwidth of up to 3.6TB/s per stack. Following HBM4 mass production, Samsung plans to ramp HBM4E production to customer schedules, strengthening its leadership in the high-bandwidth memory market crucial for advancing AI chipset performance.

In Depth

Key Findings

Samsung Electronics has announced the commencement of sample shipments for its 12-layer HBM4E, the industry’s first such high-bandwidth memory, to leading global customers. This latest generation of HBM significantly improves energy efficiency by 16% and thermal resistance by over 14% compared to its predecessor, HBM4. It delivers an astounding memory bandwidth of up to 3.6 terabytes per second (TB/s) per stack, poised to profoundly impact the market as an essential memory solution for enhancing AI chipset performance.

Technical Details

Samsung’s 12-layer HBM4E is manufactured using the company’s innovative 1c DRAM process and a 4nm foundry logic base die. This combination results in a speed improvement of over 20% compared to HBM4, achieving the ultra-fast data processing capabilities required by state-of-the-art AI applications. By leveraging advanced logic nodes in the base die, power efficiency is enhanced, and data throughput is substantially increased. As I/O density continues to scale, optimizing the base die becomes a critical factor in improving overall system efficiency. Samsung Foundry integrates advanced logic, memory, and packaging within a unified development framework, enabling system-level co-optimization to deliver the high bandwidth and energy efficiency essential for next-generation AI and HPC systems.

Background and Context

The rapid evolution of AI computing and high-performance computing (HPC) has driven demand for high-bandwidth memory to unprecedented levels. HBM is a core component of AI accelerators, and its supply has become one of the primary bottlenecks for AI server capacity. With SK Hynix having gained an early lead in HBM3E market share, Samsung’s HBM4E sample shipments intensify competition in the HBM market and represent a crucial effort by the company to reclaim leadership in the advanced memory sector. Samsung Foundry’s 2.xD Cube Packaging demonstrates its capability to handle the increasing complexity of AI systems through heterogeneous integration of multiple chips.

Strategic Significance and Outlook

Samsung plans to begin mass production of HBM4E in line with customer schedules, following the successful mass production of HBM4. The introduction of HBM4E is expected to further boost the processing power of AI applications, providing faster and more energy-efficient solutions, particularly for training and inference of large-scale AI models. Market analysts predict that HBM supply and AI server capacity will continue to be a major bottleneck for chip manufacturers. Samsung’s latest innovation is therefore crucial in alleviating this bottleneck and supporting the continued growth of the AI industry.
