Why put memory next to an AI chip?
A fast chip needs a fast way to get its data.

Feed the chip, bestie~
A simplified picture: memory supplies the data; the processor does the computing.Keep this bitHBM means high-bandwidth memory: stacked memory designed to move lots of data to a processor.
The little analogy
A busy kitchen needs ingredients close by. A powerful AI processor also needs data delivered fast enough to keep working.
Why it matters
Memory bandwidth is how much data can move in a given time. More computing power alone does not remove a data bottleneck.
