Abstract
Disclosed are devices, systems and methods for reading out data at a high speed. The data output circuit includes a line memory configured to latch a digital signal, and output the latched digital signal to a pair of column lines in response to an output control signal, a precharge circuit configured to precharge the pair of column lines with a first precharge voltage level in response to a first precharge signal, a charge circuit configured to charge the pair of column lines with a voltage, a charge controller configured to charge the charge circuit with a second precharge voltage level in response to a second precharge signal, and a sense amplifier configured to amplify an output voltage of the charge circuit in response to a sensing enable signal.
