Agentic AI scaling requires new memory architecture

Agentic AI represents a distinct evolution from stateless chatbots toward complex workflows, and scaling it requires new memory architecture.

As foundation models scale toward trillions of parameters and context windows reach millions of tokens, the computational cost of remembering history is rising faster than the ability to process it.

Organisations deploying these systems now face a bottleneck where the sheer volume of “long-term memory” (technically known as Key-Value (KV) cache) overwhelms existing hardware architectures.

Current infrastructure forces a binary choice: store inference context in scarce, high-bandwidth GPU memory (HBM) or relegate it to slow, general-purpose storage. The former is prohibitively expensive for large contexts; the latter creates latency that renders real-time agentic interactions unviable.

To address this widening disparity that is holding back the scaling of agentic AI, NVIDIA has introduced the Inference Context Memory Storage (ICMS) platform within its Rubin architecture, proposing a new storage tier designed specifically to handle the ephemeral and high-velocity nature of AI memory.
