Abstract:
A control clock generating unit outputs a clock as a control clock when a column address strobe pulse is input and fixes the control clock to a specific level when an all bank precharge signal or a refresh signal is enabled. An internal pulse generating unit outputs an external write pulse or an external read pulse as an internal write pulse or an internal read pulse in response to the control clock.
