Abstract:
A semiconductor device comprising:an internal voltage line; andinternal voltage generation circuitry for generating an internal voltage on said internal voltage line,said internal voltage generating circuitry including:a reference voltage generating circuit for generating a reference voltage;a capacitance element;a difference detection circuit for changing a charged voltage of said capacitance element in a one-way direction according to a difference between said reference voltage from said reference voltage generating circuit and the internal voltage on said internal voltage line;a current drive element having a control gate, for causing a current flow between a power supply node and said internal voltage line according to the charged voltage of said capacitance element, said capacitance element being coupled with the control gate of the current drive element; anda precharge circuit for precharging the control gate of the current drive element through precharging of said capacitance element to a predetermined voltage to make the current drive element non-conductive in response to a precharge instruction.
