## Summary

arXiv has published a survey that systematically reviews the memory mechanisms of long-horizon robot Vision-Language-Action (VLA) models, dividing them by memory scope and persistence into five representative paradigms and one emerging frontier. The survey compares representative VLA memory systems across memory characteristics, architectural complexity, and open-source maturity, finding a trade-off in which greater architectural complexity is generally accompanied by lower open-source maturity. It also discusses key challenges in building full-lifecycle memory systems, including efficient memory management and lifelong knowledge evolution.
