技术简介

HBM用于AI处理器旁处理大量数据。4
HBM, or high-bandwidth memory, is a type of advanced memory used alongside AI processors to handle large amounts of data.
高带宽内存的先进封装将多层内存芯片垂直堆叠，缩小占地。5
This sophisticated process involves vertically stacking multiple layers of memory chips on a smaller footprint to reach higher computational performance and energy efficiency.
三星HBM4以12层堆叠提供24GB至36GB容量。2
Through 12-layer stacking technology, Samsung offers HBM4 in capacities ranging from 24 gigabytes (GB) to 36GB.
三星HBM4每堆叠带宽最高3.3TB/s，较HBM3E提高至2.7倍。2
Also, total memory bandwidth per single stack is increased by 2.7x compared to HBM3E, to a maximum of 3.3 terabytes-per-second (TB/s).
HBM4是HBM3E的后继，三星称其11.7Gbps引脚速度为HBM3E最高9.6Gbps的1.22倍。2
This represents a 1.22x increase over the maximum pin speed of 9.6Gbps of its predecessor, HBM3E.
