ABSTRACT:
A semiconductor device can accurately control the timings of various signals used in the semiconductor device using a simple configuration. The semiconductor device includes first fuse units which output first fuse signals, respectively, a first decoder which receives the first fuse signals respectively output from the first fuse units, and decodes the received first fuse signals, thereby outputting a plurality of first control signals, a first delay which controls a setup/hold time of input data in response to the first control signals, a second decoder which receives the first fuse signals, and decodes the received first fuse signals, thereby outputting a plurality of second control signals, a second delay which controls a DQSS time of a clock with respect to a data strobe signal in response to the second control signals, second fuse units which output second fuse signals, respectively, and a third decoder which receives the second fuse signals respectively output from the second fuse units, and decodes the received second fuse signals, thereby outputting a plurality of third control signals. Each of the first and second delays is determined to be enabled or disabled in response to a selected one of the third control signals.
