Abstract:
1. A charge pump circuit, comprising: a plurality of capacitors configured to perform a charge pumping operation to generate a boosted voltage by boosting an input voltage in accordance with a boosting mode; a switch controller configured to generate one or more switch control signals according to boosting mode information, the generated switch control signals being configured according to the boosting mode information to provide an initialization period during which a voltage level charged in one or more of the plurality of capacitors is changed according to a new boosting mode, the initialization period being provided prior to generation of a new boosted voltage by boosting the input voltage in accordance with the new boosting mode, the new boosting mode corresponding to a change in the boosting mode information occurring during the charge pumping operation; and a plurality of switches configured to control the plurality of capacitors according to the generated switch control signals.
