    摘要: A semiconductor memory device comprises a memory cell array, a defective address programming means, a redundant enable signal generating means, an output means, and a mode control signal setting means. The memory cell array comprises a plurality of memory cells. The defective address programming means programs a redundant control signal and a defective address of a defective memory cell among the plurality of the memory cells at a package level in response to a first control signal and an address signal applied from an external portion. The redundant enable signal generating means generates a comparison coincident signal in response to the redundant control signal when the address is consistent with the defective address. The output means outputs the comparison coincident signal to an external portion in response to a second control signal during a test operation. The mode control signal setting means sets a state of the first and second control signals in response to a command signal and a mode setting signal applied from an external portion.

    摘要: A fuse circuit according to the present invention includes first and second fuses, each of which has a first end and a second end. The first and second ends of the first fuse are connected in a straight line. The first end of the second fuse is spaced by a first interval from the first end of the first fuse, and the second end thereof is spaced by a second interval from the second end of the first fuse. The first ends of the first and second fuses have the same widths as those of the second ends thereof. Alternatively, the first ends of the first and second fuses have narrower widths that those of the second ends thereof.
