High Bandwidth Memory (HBM) is a type of computer memory designed to provide high data transfer rates and increased bandwidth compared to traditional memory types like DDR (Double Data Rate) RAM. HBM achieves this by stacking memory chips vertically and connecting them with a wide interface, allowing for faster communication between the memory and the processor. This technology is particularly beneficial for applications that require rapid data processing, such as graphics processing units (GPUs) and high-performance computing systems. By using HBM, these systems can handle large datasets more efficiently, improving overall performance in tasks like gaming, scientific simulations, and machine learning.
