HBM4

High-Bandwidth Memory 4 (HBM4) is Samsung's most advanced memory chip for powering artificial intelligence systems. HBM4 addresses a fundamental performance challenge in AI infrastructure: accelerating data movement between processors and memory. By providing high-bandwidth connections, it enables faster processing of the large datasets and complex models that AI workloads require.

Samsung has achieved significant commercial success with HBM4, generating over $1 billion in sales while targeting $10 billion in revenue. This growth reflects strong demand from data centers and cloud providers expanding their AI infrastructure. As AI systems become increasingly complex and data-intensive, high-bandwidth memory has become essential to modern data center architectures supporting both model training and inference workloads.
