Memory Types & Architecture for AI Agents

How agents remember — semantic/episodic/procedural long-term memory types, why memory-less agents are a blank slate every interaction, and the 5-part memory architecture (short-term, long-term, entity, contextual, user).

🎓 Learning objectives

  • Distinguish semantic, episodic, and procedural long-term memory in agents, paralleling human memory types
  • Explain why a memory-less agentic system is a 'blank slate' on every interaction
  • Describe the 5-part memory architecture (short-term, long-term, entity, contextual, user memory) and what each stores
  • Recognize memory as a system-design problem, not a property of the LLM itself
