Patent ID: 8493135

Claim:
A semiconductor integrated circuit, comprising: a pre-charge signal generator configured to pre-charge a plurality of oscillation signals to a certain voltage level in a pre-charge mode, wherein the pre-charge signal generator comprises: a first storage unit configured to store a first pre-charge oscillation signal in response to a reference oscillation signal; a feedback unit configured to feed back a second pre-charge oscillation signal; a second storage unit configured to store the second pre-charge oscillation signal corresponding to an output signal of the first storage unit in response to the reference oscillation signal; a pre-charge signal output unit configured to output a pre-charge signal in response to the first pre-charge oscillation signal and the second pre-charge oscillation signal; and a voltage level setting unit for setting a voltage level of the first pre-charge oscillation signal in response to a power up signal provided during an initial operation period.
