| Zusammenfassung: | The present invention includes storing in a main memory data block tags corresponding to blocks of data previously inserted into a buffer cache memory and then evicted from the buffer cache memory or written over in the buffer cache memory. Counters associated with the tags are updated when look-up requests to look up data block tags are received from a cache look-up algorithm. |
