A prefetching scheme to detect when a load misses the lower level cache and hits the next level cache. Consequently, the prefetching scheme utilizes the previous information for the cache miss to the lower level cache and hit to the next higher level of cache memory that may result in initiating a sidedoor prefetch load for fetching the previous or next cache line into the lower level cache. In order to generate an address for the sidedoor prefetch, a history of cache access is maintained in a queue.
