This survey asks how close AI memory systems are to human memory and organizes the answer into three parts: implicit memory (inside the model), explicit memory (outside storage you can look up), and agentic memory (what an AI agent keeps over time to plan and act).
SimpleMem is a new memory system that helps AI remember long conversations without wasting space or tokens.
This survey explains how AI agents remember things and organizes the whole topic into three clear parts: forms, functions, and dynamics.
