SRAM and Memory Hierarchy

We have written about the role of SRAM in the memory hierarchy, but the quick recap is that SRAM is very fast (low latency and high bandwidth) but this comes at the expense of density and therefore cost.

Evidence

memory hungry attention is performed on GPUs that come with a lot of fast (but not SRAM fast) memory capacity

② Atomic Claim

記憶體需求高的 attention 則由具備大量高速記憶體容量的 GPUs 執行，雖然其速度仍不及 SRAM。

• Mapping Status: COMPLETE

③ Semantic Frame

{
  "attribute": "CAPACITY",
  "context_nodes": [
    {
      "id": "04_knowledge_base/SRAM",
      "label": "SRAM"
    }
  ],
  "entity": {
    "id": "04_knowledge_base/GPU",
    "label": "GPUs"
  },
  "frame_type": "ATTRIBUTE",
  "qualifiers": {
    "condition_text": null,
    "numeric_mentions": [],
    "temporal_mentions": []
  },
  "value": {
    "numeric_mentions": [],
    "value_text": "記憶體需求高的 attention 則由具備大量高速記憶體容量的 GPUs 執行，雖然其速度仍不及 SRAM。"
  }
}

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
entity	GPUs	GPU
context_0	SRAM	SRAM

⑤ Human Review

請在 Properties 逐項確認：

• 原文 → Atomic Claim 是否忠實
• Atomic Claim → Semantic Frame 是否忠實
• Canonical Entity mapping 是否正確
• Epistemic mode 是否保留原文語氣
• 最後選擇 review_action
