Embodiments of an invention for using a translation lookaside buffer to manage protected micro-contexts are disclosed. In one embodiment, an apparatus includes an interface and memory management logic. The interface is to perform a transaction to fetch information from a memory. The memory management logic is to translate an untranslated address to a memory address. The memory management logic includes a storage location, a series of translation stages, determination logic, and a translation lookaside buffer. The storage location is to store an address of a data structure for the first translation stage. Each of the translation stages includes translation logic to find an entry in a data structure based on a portion of the untranslated address. Each entry is to store an address of a different data structure for the first translation stage, an address of a data structure for a successive translation stage, or the physical address. The determination logic is to determine whether an entry is storing an address of a different data structure for the first translation stage. The translation lookaside buffer is to store translations.
