Patent ID: 8134858

Claim:
A semiconductor device comprising an internal voltage generator circuit said internal voltage generator circuit comprising: a first transistor having a first and a second main electrode and a control electrode; a control circuit controlling a voltage between said second main electrode and said control electrode of said first transistor such that a voltage at said first main electrode of said first transistor remains at a predetermined voltage; a second transistor having a first and a second main electrode and a control electrode, a voltage between said second main electrode and said control electrode of said first transistor being applied to between said second main electrode and said control electrode of said second transistor; a load circuit connected to said first main electrode of said second transistor, wherein said second transistor is larger in current supply capability than said first transistor; and a switch disposed between said first main electrode of said second transistor and said load circuit, wherein a first and a second internal voltage generator circuits are provided as two of said internal voltage generator circuits, each of said first and said second internal voltage generator circuits having a variable resistor connected to said first main electrode of said first transistor, said load circuit is a storage element storing information corresponding to a High level or a Low level, and said variable resistor included in said first internal voltage generator circuit has a resistance value previously set such that said information corresponding to said High level can be stored in said storage element, and said variable resistor included in said second internal voltage generator circuit has a resistance value previously set such that said information corresponding to said Low level can be stored in said storage element.
