Abstract
A circuit for controlling an internal voltage is provided. The A circuit for controlling an internal voltage, comprising: a level detector configured to detect a voltage level of a core voltage to generate a core voltage level detection signal; a release controller configured to generate a release control signal according to the core voltage level detection signal; and a core voltage release driver configured to release the core voltage according to the release control signal.

A circuit for controlling an internal voltage, comprising:
- a level detector configured to detect a voltage level of a core voltage to generate a core voltage level detection signal;
- a release controller configured to generate a release control signal according to the core voltage level detection signal;
- and
- a core voltage release driver configured to release the core voltage according to the release control signal.
A circuit for controlling an internal voltage, comprising:
- a bank controller configured to generate a first signal which is activated when an overdriving operation is finished and deactivated when a precharge signal is input, during an active period;
- a level detector configured to compare a voltage level of a core voltage and a voltage level of a reference voltage to generate a core voltage level detection signal, while the first signal is activated;
- a release controller configured to generate a release control signal according to the core voltage level detection signal, while the first signal is activated;
- a core voltage release driver configured to release the core voltage according to the release control signal;
- and
- a core voltage active driver configured to keep the core voltage at a target voltage level during the active period.
