An apparatus and method utilize compressed cache lines that incorporate embedded prefetch history data associated with such cache lines. In particular, by compressing at least a portion of the data in a cache line, additional space may be freed up in the cache line to embed prefetch history data associated with the data in the cache line. By doing so, long-lived prefetch history data may essentially be embedded in a cache line and retrieved in association with that cache line to initiate the prefetching of additional data that is likely to be accessed based upon historical data generated for that cache line, and often with no little or no additional storage overhead.
