ABSTRACT:
A data output circuit of a memory device comprises an output enable signal generating unit, an output driving unit, an output driving unit and an output enable control unit. The output enable signal generating unit generates a reference output enable signal in response to a read command and outputting a plurality of output enable signals in response to a rising DLL clock and a falling DLL clock. The output driving unit drives data synchronously with respect to the rising DLL clock and the falling DLL clock in response to the output enable signals at a read mode. The output enable control unit disables the falling DLL clock when the output enable signals are all disabled. As a result, current consumption is reduced because the falling DLL clock is generated only when the output enable signal is generated.
