# Memory integrations

> Persist short-term and long-term agent memory with LangGraph checkpointers and stores.

Memory integrations provide persistent backends for [short-term memory](/oss/python/langchain/short-term-memory) (checkpointers) and [long-term memory](/oss/python/langchain/long-term-memory) (stores).

## Short-term memory (checkpointers)

## Long-term memory (stores)
