A landmark 102-page survey by researchers across the National University of Singapore, Oxford, Peking University, and other leading institutions has mapped the emerging AI agent memory ecosystem. The central thesis is unambiguous: memory is not a peripheral feature but a foundational primitive in the design of future agentic intelligence.
This analysis synthesizes the key findings from this comprehensive research, providing a strategic framework for understanding how memory transforms static LLMs into adaptive agents capable of genuine autonomy.
The research organizes agent memory across three dimensions:
Forms: What carries the memory? Token-level (explicit, addressable), Parametric (encoded in weights), and Latent (hidden states and embeddings). Each form offers different trade-offs between transparency, efficiency, and capability.
Functions: Why does the agent need memory? Factual memory stores what the agent knows. Experiential memory captures how the agent improves. Working memory manages what the agent is currently processing.
Dynamics: How does memory operate over time? Formation extracts memories from experience. Evolution refines and consolidates. Retrieval enables utilization at the right moment.
100+ Systems Mapped
The survey catalogs over 100 memory systems across the ecosystem—from platforms like MemGPT, Mem0, and Zep to vector databases (Pinecone, Chroma, Milvus) to orchestration layers (LangChain, LlamaIndex, AutoGen). Each serves a specific function in the memory stack.
Strategic Takeaway
Memory is the foundational primitive for autonomy. Winners in the agent economy will master the triangle: persistent ↔ adaptable ↔ autonomous. Without robust memory systems, AI agents cannot maintain behavioral consistency, learn from experience, or adapt to evolving environments—the very capabilities that define the transition from narrow AI tools to genuinely autonomous systems.
