# IOInterleavedMemoryDescriptor

The IOInterleavedMemoryDescriptor object describes a memory area made up of portions of several other IOMemoryDescriptors.

## Declaration

```occ
class IOInterleavedMemoryDescriptor : IOMemoryDescriptor
```

## Overview

Overview The IOInterleavedMemoryDescriptor object represents interleaved ranges of memory, specified as an ordered list of portions of individual IOMemoryDescriptors. The portions are chained end-to-end to make up a single contiguous buffer.
