PURPOSE: A semiconductor memory device is provided to minimize current consumption and toggle an inner clock signal by generating the inner clock signal toggled in a necessary section for a circuit operation. CONSTITUTION: A plurality of inner clock generators(230,240) receive an outer clock signal. A plurality of inner clock generators generate a plurality of inner clock signals in response to a plurality of clock control signals. A clock control unit(220) generates a plurality of clock control signals for limiting a toggling operation for each inner clock signal according to an operation mode defined by a plurality of outer command signals. A clock buffering unit(210) buffers the outer clock signal. |
