    摘要: A shift information latch circuit includes a plurality of latch portions provided corresponding to memory cell rows, respectively, and a fuse circuit transmitting fuse data produced corresponding to an address of a faulty memory cell row. The plurality of latch portion successively receive fuse data, and each transmit a shift control signal instructing a shift operation. In response to this shift control signal, a row decoder and a match line amplifier execute a shift operation for repairing the faulty memory cell row. In this structure, a decoder circuit decoding the address of the faulty memory cell row is not arranged so that a whole area of the circuits executing the shift operation is reduced, and the shift operation can be easily executed.

    摘要: A plurality of content-addressable-memory sub-arrays simultaneously performs a parallel comparison between data sequences arranged in a row direction of memory cells and a search data sequence input from outside, and outputs a result of the comparison for each data sequence. A first input pin receives an input of the search data sequence. A second input pin receives an input of a search data sequence arbitrarily designating a content-addressable-memory sub-array. Each of the content-addressable-memory sub-arrays includes an activation control unit that controls activation of the content-addressable-memory sub-arrays based on the search data sequence.

    摘要: Data supplied to a particular data input/output terminal is selected and the selected data is subjected to logic change for each memory cell based on mode setting data from a changing mode setting circuit and is simultaneously written into memory cells simultaneously selected in a memory array. After a reading logic changing circuit changes the data of these simultaneously selected memory cells in the same manner as the writing logic changing circuit does, a coincidence/non-coincidence among the logics of these data is determined, and a signal representing a logic in coincidence is output if a coincidence is found. Thus, testing can be achieved at a high speed and accurately, using test data having various patterns, without increasing the number of data input/output terminals used in the testing operation.

    摘要: In a semiconductor memory device, in a normal operation, data is written to selected four memory cells in accordance with external write data DQ0 to DQ3 applied to four data input/output terminals. In test mode, same data is commonly written to the selected four memory cells in accordance with write data DQ applied to one data input/output terminal. In the test mode operation, signal transmission between the remaining three data input/output terminals and the corresponding input buffer circuits is cut off by a CMOS logic gate provided therebetween and controlled in accordance with a test mode designating signal /TE.
