Abstract
A memory system is provided for storing multiple data types. The memory system includes a main memory, a local cache, and a translation unit. The local cache has multiple entries, each of which includes a data field to store data and a status field to indicate a storage state for the stored data. The translation unit includes a translation lookaside buffer (TLB) and a status-cache (STC). The TLB stores address translations for data in the main memory, and the STC stores storage states for data indicated by the address translations.
