There is no such thing as 'cache memory' in Windows Phone 7. Isolated Storage allows you to store data as key/value pairs, files and folder or in a database, as detailed in the overview found in MSDN. It is 'isolated' in the sense that this storage is not shared between applications.

Your reference to 'cache memory' might be bitmap caching? This is a technique that Silverlight uses to cache rendered regions on the screen. See this SO question:

BitmapCache? When and how to use?

  • I have downloaded 200 images from a URL and stored in isolated storage when the application is started..Shall i retrieve the images from that storage while in offline...is it permanent once i stored the data in iso store.. – SENTHIL KUMAR Mar 07 '12 at 08:34
  • It depends on what settings you use. One more thing, it is not persistent in emulators but it is persistent in WP(once again the settings matters!) –  Mar 07 '12 at 12:18
