Earlier this year the company started mass production of its HBM4 product earlier this year. High Bandwidth Memory, HBM, stacks DRAM die on top of each other with massive parallel connectivity to maximize the data bandwidth. HBM memory is used in conjunction with GPUs and other domain specific processors in a chiplet architecture, storing data to support AI training and inference workloads. The front and back of the HBM4e HBMs are shown below.HBM4E samples showing front and back of HBMSamsungCurrently HBM memory is in high demand with not enough production to meet that demand with consequently high prices and with big users such as hyperscale data centers having long term contracts with suppliers to get the HBM they need.According to the company, Samsung’s HBM4E delivers a stable pin speed of 14 gigabits-per-second (Gbps), with performance scalable up to 16Gbps to support increasingly intensive data processing requirements. This represents more than a 20% increase over its HBM4, while delivering memory bandwidth of up to 3.6 terabytes-per-second (TB/s) per stack, helping maximize computing performance for large language models (LLMs) and next-generation AI systems.Samsung’s 12-layer HBM4E is offered in a 48-gigabyte (GB) capacity, representing more than a 30% increase over the previous generation, with plans to expand the lineup to include 32GB (8-layer) and 64GB (16-layer) configurations in accordance with customer requ...
