Abstract
A data output method and data output circuit capable of increasing data output speed by reducing clock power while increasing sensing speed are provided. The data output method includes (a) precharging output terminals to a precharge voltage lower than a supply voltage; and (b) outputting differential output signals to the output terminals in response to differential input signals. In step (a) the output terminals are precharged in response to a clock signal having a first state, and in step (b) the differential signals are output to the output terminals in response to the clock signal having a second state. The voltage swing of the clock signal is set lower than the precharge voltage. The method further includes latching the differential output signals.
