High Bandwidth Memory (HBM) is a cutting-edge memory architecture which employs a 3D stacking method to improve data transfer speed and efficiency to a great extent. It stacks multiple DRAM dies vertically using through-silicon vias (TSVs) and microbumps, which drastically shortens the interconnects between memory layers. This design allows for a distributed interface across the host compute die, enhancing overall system performance by maximizing bandwidth, which can reach up to 512 GB/s. Commonly used in high-performance computing and AI, HBM is ideal for applications requiring rapid access to large volumes of data. Exploring further, you'll uncover its evolving role in next-generation computing technologies.
