Classification: CPC G | IPC G

Claim 13:
14. An electronic device comprising:
an internal mode control circuit suitable for generating an internal voltage control signal based on a refresh cycle when an internal mode is performed in a self-refresh operation;
a boost control signal generation circuit suitable for generating a boost control signal depending on whether the internal mode is performed in the self-refresh operation; and
an internal voltage generation circuit suitable for adjusting a level of an internal voltage for a refresh operation based on the internal voltage control signal and the boost control signal,
wherein, when the internal mode is performed, the internal mode control circuit activates a burst control signal within at least one refresh cycle whenever a burst refresh cycle elapses,
wherein the burst refresh cycle is set larger than the refresh cycle,
wherein, when the internal mode is performed, the internal mode control circuit counts an input of a refresh cycle signal and sets the burst refresh cycle in which the burst control signal is generated whenever the input of the refresh cycle signal is counted multiple times, and
wherein the refresh cycle signal is activated every refresh cycle.
