SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PURPOSE: A semiconductor integrated circuit is provided to minimize current consumption of a duty correcting circuit by limiting a toggling section of a delayed clock signal from a delay locked loop within a preset section. CONSTITUTION: A delay locked loop generates a delayed clock signal by delaying a reference clock signal corresponding to delay time. A clock transmitting unit(230) transmits the delayed clock signal in response to a clock transmission signal. A duty correcting circuit(240) corrects a duty by receiving the clock signal transmitted from the clock transmitting unit. A clock transmission signal generating unit(260) generates a clock transmission signal according to a burst length(BL) information and a command.
