The MESI protocol, also known as the Illinois protocol, is a widely used Invalidate-based cache coherence protocol that supports write-back caches. Developed at the University of Illinois, it reduces bandwidth waste common in write-through caches by maintaining a "dirty state" to indicate discrepancies between cache and main memory data. The protocol enhances performance by reducing main memory transactions and requiring cache-to-cache transfers when a block resides in another cache.
