    摘要: A semiconductor memory device includes a plurality of memory blocks, i main row or column select lines extending over the plurality of memory blocks, and a decoder for selecting one of the main row or column select lines in accordance with an applied address signal. The decoder includes i outputs. Each of the memory blocks includes a plurality of memory cells arranged in rows and columns and at least (i+1) sub row or column select lines each for selecting one row or one column of memory cells. A shift redundancy circuit is provided for each of the memory blocks, for connecting the main row or column select line and the sub row or column select line. The shift redundancy circuit includes a switch circuit for connecting one main row or column select line to one of the plurality of adjacent sub row or column select lines, and a circuit for setting a connection path of the switch circuit. The shift redundancy circuit connects successively adjacent sub row or column select lines to main row or column select lines in one to one correspondence except a defective sub row or column select line associated with a defective bit.

    摘要: A portion of a cell plate 91 extending upon a field oxide film 107a and a silicon oxide film 123 is referred to as a lower layer interconnection film 109. The lower layer interconnection film 109 has a concave shape. A through hole 95a is formed in a silicon oxide film 93 reaching the bottom of the concave shape lower layer interconnection film 109. The depth of the through hole 95a is greater in comparison with the case where a through hole is formed on an upper face portion 123a of the silicon oxide film 123. Because the depth of through hole 95a is great, the thickness of the tungsten film 101a formed in through hole 95a becomes thicker. This eliminates the problem that all the tungsten film 101a in the through hole 95a, and then a portion of the lower layer interconnection film 109 are overetched. Therefore, electrical connection between the upper layer interconnection layer 103a and the lower layer interconnection layer 109 can be ensured.

    摘要: An XOR gate receives an input from a pair of read data lines to output a self-precharge signal when there is an increased potential difference between the paired read data lines. Thus, immediately after the increased potential difference between the paired read data lines occurs upon issuance of a read command, a precharge operation is autonomically performed. Therefore, no external precharge command is necessary when the read command is issued and thus a higher-speed operation is easily achieved.

    摘要: A semiconductor integrated circuit device in which circuit functions can be remedied or changed by severing at least a portion of a circuit pattern and a method for producting such semiconductor integrated circuit device. The circuit pattern is formed on the semiconductor substrate. A field shield plate is formed on the major surface of the semiconductor substrate for electrically separating respective elements constituting the circuit. The circuit pattern includes a fuse element. The fuse element is provided on the field shield plate. The portion of the field shield plate lying directly below the fuse element is isolated from other portions of the field shield plate. In such semiconductor integrated circuit device, the portion of the field shield plate lying directly below the fuse element is separated from other portions of the field shield plate, so that short-circuiting between the semiconductor substrate and the field shield plate cannot occur even when the laser beam is irradiated with a laser beam deviation at the time of severing of the fuse element.
