Definitions of CACHE COHERENCY
Sort: Oldest first
(Or "cache consistency") /kash koh-heer'n-see/ Thesynchronisation of data in multiple caches such that readinga memory location via any cache will return the most recentdata written to that location via any (other) cache.Some parallel processors do not cache accesses to sharedmemory to avoid the issue of cache coherency. If caches areused with shared memory then some system is required to detectwhen data in one processor's cache should be discarded orreplaced because another processor has updated that memorylocation. Several such schemes have been devised.
