HBM, or High Bandwidth Memory, is a type of computer memory designed to provide faster data transfer rates compared to traditional memory types like DDR4. It achieves this by stacking memory chips vertically and connecting them with a wide interface, allowing for more data to be processed simultaneously. This makes HBM particularly useful in applications that require high performance, such as graphics processing units (GPUs) and supercomputers. Developed by Micron Technology and SK Hynix, HBM is often used in advanced computing systems, including artificial intelligence and machine learning applications. Its ability to handle large amounts of data quickly helps improve overall system performance, making it a preferred choice for modern high-performance computing tasks.
