Abstract
The present invention discloses a semiconductor memory device that includes first and second memory banks. A first control signal generating circuit generates a first control signal responsive to an external clock. A first data output circuit transmits a first output data responsive to the first control signal. An internal clock signal generating circuit outputs first and second buffered clock signals responsive to the external clock. A second control signal generating circuit generates a second control signal responsive to the first buffered clock signal and the first control signal. A second data output circuit transmits a second output data responsive to the second control signal. A third data output circuit transmits a third output data responsive to the first and second buffered clock signals. The present invention prevents data read errors resulting from variations in power supply voltage and temperature.
