    摘要: A semiconductor memory device has a plurality of memory cell arrays; input and output sections each provided so as to correspond to each of the memory cell arrays; and an allocating section provided between the memory cell arrays and the input and output sections, for allocating one of the memory cell arrays to one of the input output sections in ordinary mode, and a plurality of the memory cell arrays to one of the input and output sections in test mode. In the operation test mode, since only a part of the input and output sections are used, it is possible to decrease the number of chips connected to the I/O pins (whose maximum number is limited) of the tester so as to be testable simultaneously, so that the number of chips whose operation tests can be implemented simultaneously can be increased, thus reducing the time required for the operation test of the memory device as a whole.

    摘要: A fault after an assembling process is saved by using a tester. An error detector circuit compares read data from a memory cell and data from an external input/output terminal by means of a comparator circuit, thereby determining whether a memory cell is good or faulty. The error detector circuit outputs a sense signal COMPERR in the case where the memory cell is faulty. A self fuse program circuit causes a latch circuit LAi to latch an external address as a save address upon receipt of the sense signal COMPERR. By a counter Ci and a switch circuit SW, programming of a save address is carried out by transferring the save address latched at the latch circuit LAi to a fuse program circuit FPi on one bit by one bit basis.
