Summary:A memory module comprises a plurality of memory chips, data input/output terminals, and switching means. One word in a memory chip comprises a plurality of bits, and each memory chip includes a number of input/output terminals corresponding to one word. The number of data input/output terminals is less than the total number of input/output terminals of the memory chips. Switching means switches a connection between input/output terminals of the memory chips and data input/output terminals. Only those input/output terminals of the memory chips which are connected to non-defective bits are connected to the data input/output terminals.
