Where Samsung Electronics sits in the stack
Samsung Electronics's placements in this catalog cover 10 parts, from layer 1 (compute silicon & packaging) to layer 2 (memory & storage). 4 of them are tagged constrained, meaning a sourced shortage rather than a long lead time. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Leading-edge foundryconstrained — The advanced-node semiconductor fabs that manufacture the compute dies for essentially every AI accelerator on the market.
- 2.5D/3D advanced packagingconstrained — The 2.5D/3D processes that combine a compute die, HBM memory stacks, and a substrate into one finished package — the step that turns silicon into a shippable AI accelerator.
- HBMconstrained — High-bandwidth memory stacked directly on the same package as an AI accelerator, giving the GPU or ASIC very fast, close-range access to the memory it needs to stay fed.
- DRAMconstrained — Off-package system memory — DDR5 modules for host CPUs and LPDDR5X soldered near Nvidia's Grace CPU — that holds the working data a server's processors operate on.
- Interposers, silicon bridges, RDL — The silicon interposers, bridges, and redistribution layers that route signals between a compute die, HBM stacks, and the substrate inside an advanced package.
- and 5 more in the table above.
