Can Lookup-Based Memory Revolutionize Transformers? Inside the STEM Architecture

The STEM architecture replaces the Transformer feed‑forward network with a static token‑indexed embedding table, enabling lookup‑based memory that decouples capacity from compute, improves training stability, expands addressable memory, and delivers consistent performance gains on long‑context and knowledge‑intensive tasks.
