What is Silicon interposer?
A silicon intermediate substrate that holds chips side by side and connects them densely with fine wiring. It is used to connect GPUs and HBM, among other things.
Silicon interposer in the explanations
A silicon interposer is an intermediate silicon substrate with fine wiring made by semiconductor processes.
Which correctly describes the role of the silicon interpose…Placing the GPU and HBM side by side on a silicon interposer, where fine wiring can be made, connects them over short distances with many wires, achieving the very high memory bandwidth AI computation needs.
In AI GPUs, what is the main reason the GPU chip and HBM ar…It is used in 2.5D packaging, placed beside the processor on a silicon interposer or similar, and is mounted on AI GPUs and other devices.
Which correctly describes HBM (High Bandwidth Memory)?
