A new study (arXiv:2606.06448) profiles ten representative memory systems with phase-aware measurement and finds that picking a memory design mostly relocates cost between the write path (construction) and the read path (retrieval) rather than eliminating it. It ships ten concrete recommendations covering construction scheduling, capability floors, and freshness-versus-latency tradeoffs. The actionable bit: measure construction, retrieval, and generation cost separately before you adopt a memory stack, and match the design to your actual read/write ratio. There's no free memory architecture, only a choice about which path eats the cost.
