The Comprehensive Insights into HBM Performance

Introduction

HBM (High Bandwidth Memory) has emerged as a crucial component in modern computing systems. This article aims to provide a comprehensive overview of HBM performance and its related developments.

The Unusual Case of IEC-Robust IC with Low HBM Performance

In certain cases, ICs that are robust to on-chip IEC 61000–4–2 ESD level events may consistently fail at low HBM levels (<2KV). The causes for this miscorrelation need detailed investigation, and a more reliable indicator for HBM robustness is awaited.

Samsung Electronics' Plans for Custom HBM

Samsung Electronics has announced plans to develop diverse custom HBM memories in the HBM4 generation. Custom HBM is expected to become a reality and offer different choices in terms of PPA (Performance, Power, and Area) compared to standard products. Two possible custom HBM forms have been described, which could simplify the data path and reduce power consumption and area.

HBM Driven by AI

The demand for HBM is soaring due to the continuous growth of applications like AI accelerators, graphics processors, and high-performance computing. The AI wave has led to a situation where HBM is often out of stock as it is the preferred storage for data in creating large models. Moreover, the need to enhance performance through multi-layer high-density construction and the limitations of SRAM have pushed the demand for HBM to new heights.

The Features and Advancements of HBM3

HBM3 offers several improvements over HBM2E, such as higher capacity, more advanced RAS functions, and lower power consumption. The memory capacity is increasing, and new technologies like 8-layer and 12-layer stacking enable larger capacities. HBM3 is being used in various high-performance computing applications.

The Future of HBM4

Samsung Electronics is working on developing large-capacity HBM4 memories, and its expected production in the coming year holds great promise for further advancements in the field of high-performance computing and memory technologies.

In conclusion, HBM performance is a dynamic and evolving field with continuous innovations and developments to meet the growing demands of modern computing.
