摘要
An electric potential switching circuit has an electric potential control circuit, an output circuit, and a precharge circuit connected to the output circuit. The electric potential control circuit generates a reference electric potential associated with an operation mode of a flash memory. The output circuit generates at an output terminal an output electric potential corresponding to the reference electric potential when enabled, and sets the output terminal to a high impedance state when disenabled. The output circuit is disenabled when the operation mode is switched from a first mode to a second mode. While the output circuit is disenabled, the electric potential control circuit switches the reference electric potential from a first electric potential associated with the first mode to a second electric potential associated with the second mode, and the precharge circuit precharges the output terminal in response to the reference electric potential.
