PURPOSE: A cache consistency maintaining method is provided, which adjusts a performing sequency of a transaction and maintains a cache consistency in an optimum condition. CONSTITUTION: The cache consistency maintaining method comprises the steps of: (ST100, ST102) sensing a transaction on a local bus when the cache transaction is occurred on the local bus and successively storing the transaction to a queue memory; (ST104) performing a consistency test to an entire cache transaction stored in the queue memory for embodying a synchronization of each cache memory in a storing condition of the transaction; (ST106, ST108, ST110) and renewing data before a read transaction when the read transaction and a writing transaction to the cache memory are occurred and providing the data to a corresponding processor. Thereby, it is possible to improve the entire performance of the system.
