Samsung Electronics Co., Ltd. (OTC:SSNLF) is one of the fastest-growing high-bandwidth memory stocks to buy. The company gave a direct HBM hook on May 29, 2026, when it began shipping 12-layer HBM4E samples to major global customers. Samsung said the product delivers a stable pin speed of 14Gbps, scalable up to 16Gbps, with memory bandwidth of up to 3.6TB/s per stack for large language models and next-generation AI systems.

The company also said the 48GB version offers more than 30% higher capacity than the previous generation, while energy efficiency and thermal resistance improved 16% and more than 14%, respectively. The update is especially relevant because Samsung combines memory, foundry, logic design, and advanced packaging, using its 1c DRAM process and 4nm logic base die for HBM4E. Its latest reported quarter also showed 69% year-over-year revenue growth, supported by AI memory demand, high-value semiconductor products, and tighter supply.
