Abstract
A precharge circuit includes a precharge unit configured to apply a voltage of a precharge voltage terminal to a data line during a precharge operation, and a sensing unit configured to disable the precharge unit by sensing the voltage of the precharge voltage terminal. The precharge circuit may control a precharge operation by sensing a change in the voltage level of the precharge voltage terminal.
