TSV: what it means.
A through-silicon via provides a vertical electrical path through silicon. Micron describes TSVs and bonding structures connecting stacked DRAM dies in HBM, helping create the wide connection architecture of the stack. (Micron: high-bandwidth memory)
The term identifies an interconnect structure, not a complete memory or processor. HBM is a memory architecture that uses such structures; a TSV alone does not specify storage capacity, speed or system compatibility. (Micron: high-bandwidth memory)
Put the definition to work.
A TSV is not the same as a plated hole in a circuit board. It belongs to the semiconductor or packaging structure rather than the ordinary PCB interconnect. (Micron: high-bandwidth memory)
Questions to ask next.
Use these questions as a reading checklist, not as a device-selection recommendation. Exact manufacturer documentation takes priority over a general definition.
- Which layers the connection crosses
- Packaging and bonding context
- Structure versus complete-device specifications
For the broader explanation, explore memory and bandwidth. This page defines the term; the companion guide connects it to the rest of the system.
Common TSV questions.
Is a TSV the same as a PCB through-hole?
No. Both involve vertical connections in a broad geometric sense, but a TSV belongs to the silicon integration structure, not the ordinary circuit-board mounting arrangement. (Micron: high-bandwidth memory)
