A comparative study on power delivery aspects of compute-in/near-memory approaches using DRAM

Lizy Kurian John, Siddhartha Raman Sundara Raman, Siyuan Ma

DRAM-based compute-in-memory creates non-traditional current demands that require power delivery network aware designs for reliable scaling.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

This survey highlights the importance of PDN-aware design for scalable and reliable DRAM-based PIM systems and outlines key future research directions.

C2weakest assumption

That the representative PIM techniques surveyed (multi-row activation, row-buffer operations, near-bank compute) sufficiently capture the full range of current-demand patterns that will appear in future DRAM-based PIM deployments.

C3one line summary

The survey proposes a taxonomy for PIM-induced current behaviors in DRAM and analyzes how representative techniques create voltage droop and thermal issues, along with mitigation strategies using existing DRAM mechanisms.
