ORage> (OR "cache consistency") /kash koh-heer' n-see/ The synchronisation of data in multiple caches such that reading a memORy location via any cache will return the most recent data written to that location via any (other) cache. Some parallel processORs do not cache accesses to {shared memORy} to avoid the issue of cache coherency. If caches are used with shared memORy then some system is required to detect when data in one processOR' s cache should be discarded OR replaced because another processOR has updated that memORy location. Several such schemes have been devised. (1998-11-10)
