The CLR maintains separate heaps for jitted code as well as the various other bits of information that's specific to types and static objects. The generic term for them is "loader heap" and it is associated with an AppDomain. Which is the basic mechanism by which assemblies, types, jitted code and statics disappear when you unload an AppDomain.

The loader heaps further sub-divide in a high frequency, low frequency and stub heap. Some background info is available in this article.
