ABSTRACT:
A method and system of maintaining coherency for a data block transferred from a main memory to a cache memory. The data transfer is recorded in a tag register in the main memory. An overwrite of the data block is detected by comparing main memory data writes with the recorded transfer. The cache memory is only notified in the event an overwrite is detected. An invalid flag is then set in the cache.
