Claim Text:
1. A semiconductor memory having a voltage generator, the voltage generator comprising: a first comparison device configured to have a first voltage input thereto, compare the first voltage with a second voltage at a first node, and to output a comparison result that causes the second voltage at the first node to be equal to the first voltage; a first capacitor connected between ground and a second node; a first switch configured to electrically connect and disconnect the first and second nodes; a current source configured to output a current to a third node; a first resistor connected between ground and the third node; a second capacitor connected between ground and a fourth node; a second switch configured to electrically connect and disconnect the third and fourth nodes; a third switch configured to electrically connect and disconnect the second node and a fifth node, and a fourth switch configured to electrically connect and disconnect the fourth node and the fifth node; and a second comparison device configured to have a third voltage input thereto, compare the third voltage with a fourth voltage, and to output an output voltage, wherein the third voltage is a voltage at the fifth node and the fourth voltage is a percentage of the output voltage.
