# Memory Domains

## Memory Domains

### Bizhawk

* FCRam(128MB): The main memory (RAM) component where most loaded data is stored. Uses ARMv6K architecture.
* VRAM(6MB): Stores data for the GPU to produce screen visuals. Uses PICA200 shader architecture.
* DSP RAM(512KB): Stores binary audio files used to recognize/produce sounds. Unknown architecture (probably raw sound data).
* N3DS Extra RAM(128MB): Extended FCRam included with the New 3DS (only used in later titles). Uses ARMv6K architecture.
* System Bus: Moves data between the different processors/components on the SoC. Uses a mixed architecture.

### Citra

* FCRam(128MB): The main memory (RAM) component where most loaded data is stored. Uses ARMv6K architecture.
* VRAM(6MB): Stores data for the GPU to produce screen visuals. Uses PICA200 shader architecture.
* DSP(512KB): Stores binary audio files used to recognize/produce sounds. Unknown architecture (probably raw sound data).
* 3DSExRam(128MB): Extended FCRam included with the New 3DS (only used in later titles). Uses ARMv6K architecture.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://corrupt.wiki/systems/nintendo-3ds/memory-domains.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
