In a processor a method for filtering stores to prevent all stores from having to snoop check against all words of a cache. The method includes implementing a cache wherein stores snoop the caches for address matches to maintain coherency; markin g a portion of a cache line if a given core out of a plurality of cores loads from that portion by using an access mask; checking the access mask upon execution of subsequent stores to the cache line; and causing a miss prediction when a subsequent store t o the portion of the cache line sees a prior mark from a load in the access mask.
