description: |
Renesas SoCs contain one or more memory controllers. These memory
controllers differ from one SoC variant to another, and are called by
different names, e.g. "DDR Bus Controller (DBSC)", "DDR3 Bus State Controller
(DBSC3)", or "SDRAM Bus State Controller (SBSC)").

Annotation
- Immediate include surface: `dt-bindings/interrupt-controller/arm-gic.h`.
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
