Abstract

PURPOSE: To improve yield by providing respective two data buses and address buses to one memory cell so as to form these in a pair, and short-circuiting between these data buses by means of bridge lines.
CONSTITUTION: Respectively a pair of data buses B, (b) and a pair of addrss buses A, (a) are prepared for one memory cell 10, and bridge lines 4 and 5 for short-circuiting these are provided between a pair of the data buses and a pair of the address buses. Further, pads 6, 7 for testing are formed to the parts connecting the bridge lines 4, 5, and respectively fusible fuses 8, 9 are formed between the pad 6 and the data buses B, (b) and between the pad 7 and the address buses A, (a). Even if disconnection occurs at the point α of the address line A1, it is possible to prevent the cell 10 from getting defective owing to disconnection by the address buses A, (a) and the bridge line 5. Even if a short circuit occurs at the point α of the address line A1, this may be eliminated by fusing the fuse 9.
