DRAM-based PIM is particularly attractive due to its high density, mature manufacturing ecosystem, and compatibility with existing systems. Recent works exploit multiple levels of the DRAM hierarchy - including subarrays, banks, and 3D-stacked organizations - to enable in-memory computation using mechanisms such as multi-row activation, row-buffer operations, and near-bank compute units. However, these approaches introduce non-traditional current de"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"This survey highlights the importance of PDN-aware design for scalable and reliable DRAM-based PIM systems and outlines key future research directions.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"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.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"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.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"DRAM-based compute-in-memory creates non-traditional current demands that require power delivery network aware designs for reliable scaling.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"1398e844179dfb19f9d0ce593c9f4e4dee594aff4beabe1bef3d5ad604829ba4"},"source":{"id":"2604.04773","kind":"arxiv","version":2},"verdict":{"id":"e9dec489-e647-4c42-9430-641a7f372ad7","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-10T18:53:26.408278Z","strongest_claim":"This survey highlights the importance of PDN-aware design for scalable and reliable DRAM-based PIM systems and outlines key future research directions.","one_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.","pipeline_version":"pith-pipeline@v0.9.0","weakest_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.","pith_extraction_headline":"DRAM-based compute-in-memory creates non-traditional current demands that require power delivery network aware designs for reliable scaling."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2604.04773/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":2,"snapshot_sha256":"af8010def7b396cfbfe4c6f8aa47fae50d1966f569d2cd765ec3a2c2f2f7a990"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
