Abstract
Apparatuses and methods for providing power for memory refresh operations are described. An example apparatus includes refresh circuits, a power amplifier, a power circuit, and a power control circuits. The refresh circuits are configured to refresh memory cells of a memory bank. The power amplifier is configured to provide power when activated to the refresh circuits. The power provided by the power amplifier has a first voltage. The power circuit is configured to receive a power supply voltage and to provide power when activated to the refresh circuits. The power provided by the power amplifier has a second voltage. The power control circuit is configured to compare the first voltage and the target voltage and to provide an activation signal to control activation of the power circuit having an active duration based at least in part on the comparison.
