Abstract
A method of detecting defective memory locations by determining a slot number corresponding to a memory address, when read data disagree with written data, determining a memory size corresponding to the determined slot number, determining relationships between data bit positions and memory module numbers according to the determined memory size, determining a memory module number as an abnormal memory according to the determined relationships, and specifying the slot number and the memory module number of the abnormal memory. Based on the specified slot number and memory module number, the defective memory module at the slot number can be quickly located and removed.
