# Memory

> Keep data in memory.

Keeps data in memory using [Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map). (default storage)

## Usage

**Driver name:** `memory`

<note>

By default, it is mounted at the top level, so it's unlikely that you will need to mount it again.

</note>

```js
import { createStorage } from "unstorage";
import memoryDriver from "unstorage/drivers/memory";

const storage = createStorage({
  driver: memoryDriver(),
});
```
