<P>PROBLEM TO BE SOLVED: To detect a bit error in a reference history without adding redundancy bit to the reference history in a cache memory device of Nway set associative system. <P>SOLUTION: This cache memory device of N way set associative system (N is an integer of 2 or more.) is provided with a way detecting part detecting a specific-strength-way based on the reference history, which a bit showing a win or lose relation between the ways and updated so as to show the specific-strength-way, and an error detecting part detecting the bit error in the reference history when the specific-strength-way is not detected by the way detecting part. <P>COPYRIGHT: (C)2004,JPO |
