INTERNAL VOLTAGE GENERATION CIRCUIT AND SYSTEM INCLUDING THE SAME
First Claim
1. An internal voltage generation circuit comprising:
- an internal voltage control circuit configured to generate an enable signal and a switch control signal based on a comparison result between a reference internal voltage and an output internal voltage;
a first internal voltage generation circuit configured to generate the reference internal voltage based on a setting code, and provide the reference internal voltage to one of the internal voltage control circuit and a node from which the output internal voltage is outputted, based on the enable signal; and
a second internal voltage generation circuit configured to generate the output internal voltage based on the switch control signal.

Abstract
An internal voltage generation circuit may be provided. The internal voltage generation circuit may include a first internal voltage generation circuit configured to provide a reference internal voltage to either an internal voltage control circuit or a node at which an output internal voltage is generated. The internal voltage generation circuit may include a second internal voltage generation circuit configured to change a level of the output internal voltage. The internal voltage generation circuit may include an internal voltage control circuit configured to compare the reference internal voltage with the output internal voltage and control the first and second internal voltage generation circuits to change the level of the output internal voltage according to a comparison.
