    摘要: The present invention provides a redundancy circuit in a semiconductor memory device which has spare memory cells which can store information that can be substituted for data of defective memory cells after the completion of the manufacturing process. If addresses designating the defective memory cells are externally input, the redundancy circuit generates a defective cell relief address signal which corresponds to the address designating the defective memory cell and is used to prevent defective data stored in normal memory cells from being output and causes correction data, to be substituted for the defective data output in correspondence with the defective cell relief address.

    摘要: A nonvolatile semiconductor memory with a unit cell structure suitable for high speed operation and a low power supply voltage. The nonvolatile semiconductor memory includes a switching circuit including block select transistors connected by its respective terminal to a corresponding bit line. This switching circuit transmits a signal only when a string to which the switching circuit corresponds is selected. A second active region having a different impurity concentration from a first active region constituting source and drain regions of memory transistors is formed at a substrate contact portion of a bit line contact portion where the memory string and bit line are connected. The impurity concentration of the second active region is lower than that of the first active region.

    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.
