    Abstract: A voltage trimming circuit including: a first resistance circuit having a first resistance value determined by up codes and down codes; a second resistance circuit having a second resistance value determined by the up codes and the down codes; and a comparator to output a voltage detection signal by comparing a voltage level of a reference voltage trimming node to that of a feedback node, wherein the voltage detection signal adjusts the up and down codes, which increase the first resistance value and decrease the second resistance value when the voltage level of the reference voltage trimming node is higher than that of the feedback node, and adjusts the up and down codes, which decrease the first resistance value and increase the second resistance value when the voltage level of the reference voltage trimming node is lower than that of the feedback node.

    Abstract: A semiconductor memory device comprises a memory cell array including segments disposed at corresponding intersections of row and column blocks, each row block including dynamic memory cells coupled to word-lines and bit-lines, a row decoder that activates a first word-line of a first row block in response to a row address, determines whether the first row block is a master block based on a first fuse information and a second row block is mapped as a slave to the master block, activates a second word-line of the second row block, and outputs a row block information signal, and a column decoder accessing a portion of first memory cells coupled to the first word-line or a portion of second memory cells coupled to the second word-line based on a column address, the row block information signal and a second fuse information.
