Abstract

A semiconductor device includes a latch circuit receiving a first signal, generated in synchronization with a clock signal, from a pulse generation circuit, and generating a second signal; a first delay circuit receiving the second signal from the latch circuit, and generating a third signal by delaying the second signal; a second delay circuit receiving the third signal from the first delay circuit, and generating a fourth signal by delaying the third signal; and a logic circuit receiving the second and fourth signals from the latch and second delay circuits, respectively, and generating a word line control signal based on one of the second signal and the fourth signal. The latch circuit generates the second signal of a first level based on the first signal, and generates the second signal of a second level, which is different from the first level, based on the third signal.
