PURPOSE: To determine in which of data, error correction code(ECC) or address a memory error a memory error is generated by retesting that position while using an address sensitive memory test pattern when the memory error is generated. CONSTITUTION: A computer system 10 is provided with a central processor 12 and a main memory 14. Address-sensitive test data are used for testing the computer system 10. When the memory error is generated or the initial test of the memory 14 shows an error, the address sensitive memory test pattern selecting that position is retested. By selecting the proper address sensitive memory test pattern, all the data bit, ECC bit and address parity bit can be tested. Thus, it can be determined which of the data, ECC or address the memory error is generated at. |
