A method of testing cache memory is proposed, which is designed for use on a memory system having a primary memory unit and a cache memory unit for testing the cache memory unit to check if the cache memory unit is normal in read/write operations. The proposed method comprises the steps of writing a block of test data into the cache memory unit; converting the test data through a first encoding process into a first block of encoded data; writing the first block of encoded data into the primary memory unlit; fetching data from the primary memory unit; converting the fetched data from the primary memory unit through a second encoding process into a second block of encoded data; and storing the second block of encoded data into the cache memory unit; and finally comparing either the first block of encoded data or the second block of encoded data against a predetermined block of reference data to check whether the read/write operation to the cache memory unit is normal.
