# Manual memory regions

```
 Action    name: ManualRegions
 
```

This command open a window with manual memory regions. In this window the user can manipulate memory region definitions: add or delete them.

Some debugger backends (e.g. the gdb backend) do not provide memory layout information. IDA needs this information in order to show the memory contents. When this information is not available, the user must specify it.

The defined memory regions will be accessible when the debugger is active. The user will be able to see the memory contents in the disassembly windows.

If no memory information is provided by the user nor by the debugger backend, IDA will assume that entire memory space is accessible. However, it is better to specify memory layout more precisely.

## 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://docs.hex-rays.com/8.5/user-guide/user-interface/menu-bar/debugger/process-memory/manual-memory-regions.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.
