Semiconductor integrated circuit device

A semiconductor integrated circuit device using precharge circuits free from the influence of a phase difference skew is provided. Each of the precharge circuits is controlled by a clock signal such that an arbitrary node in the circuit is precharged during a low level period or a high level period of the clock signal and the precharge circuit is operative during a high level period or a low level period of the clock signal. A first precharge circuit and a second precharge circuit having the same operational functions are arranged in parallel, and controlled by their respective clock signals to perform complementary operations, wherein the second precharge circuit is in an active period when the first precharge circuit is in a precharge period, and the second precharge circuit is in a precharge period when the first precharge circuit is in an active period.
