ABSTRACT:
According to embodiments of the invention, a distributed time base signal may be coupled to a memory directory which provides address translation for data located within a memory cache. The memory directory may have attribute bits which indicate whether or not the memory entries have been accessed by the distributed time base signal. Furthermore, the memory directory may have attribute bits which indicate whether or not a memory directory entry should be considered invalid after an access to the memory entry by the distributed time base signal. If the memory directory entry has been accessed by the distributed time base signal and the memory directory entry should be considered invalid after the access by the time base signal, any attempted address translation using the memory directory entry may cause a cache miss. The cache miss may initiate the retrieval of valid data from memory.
