Parallel Computing Architecture Using 3D Stacked TSV Interconnects

The patent transitions from conventional two-dimensional planar interconnects to three-dimensional vertical interconnects using through-silicon vias (TSVs). This dimensional change enables direct vertical communication between stacked computing cores and memory modules, dramatically increasing connectivity and communication bandwidth while maintaining a compact form factor that mimics the brain's three-dimensional neural structure.

The patent implements a stacked architecture where computing cores, coprocessors, and memory modules are vertically nested in multiple layers. Each layer is interconnected through TSVs, creating a nested three-dimensional structure that enables massive parallelism and high-bandwidth communication, similar to the nested organization of neurons and synapses in the human brain.

The patent uses three-dimensional stacking with vertical TSV interconnects to enable massive parallelism without proportionally increasing interconnect complexity. Multiple computing cores are arranged in vertical stacks, each core communicating directly with dedicated memory and coprocessor units through short vertical paths, eliminating the need for complex long-range horizontal interconnects required in two-dimensional architectures.

The patent divides the computing system into multiple independent but interconnected segments - computing cores, coprocessors, and memory modules - each organized in vertical stacks. This segmentation allows each unit to operate independently with dedicated resources, reducing interconnect complexity while enabling scalable parallelism through the aggregation of multiple segments.

The patent incorporates misalignment compensation mechanisms in the form of compliant interposer layers and self-aligning features that absorb and compensate for manufacturing tolerances before they affect electrical connections. These cushioning elements are built into the stacking process to preemptively handle alignment variations, reducing the stringency of precision requirements.

The patent uses intermediate interposer substrates that provide a buffer layer between stacked components. These interposers contain through-vias and routing layers that can accommodate misalignment, acting as mediators that transfer signals while compensating for positioning errors, thereby reducing the precision requirements for direct core-to-core alignment.
