Assignee: SANDISK TECHNOLOGIES, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. An apparatus comprising:
a charge pump having a clock input configured to receive a clock signal, a power input configured to receive a supply voltage, and an output, wherein the charge pump is configured to provide an output voltage at the output that depends on the clock signal; and
one or more control circuits in communication with the charge pump, the one or more control circuits configured to connect to a memory structure comprising memory cells and control lines, wherein the one or more control circuits are configured to:
provide the output voltage to a control line in the memory structure;
operate the charge pump in a current regulation mode in which a first clock signal based on the output voltage is provided to the clock input to regulate input current at the power input to a target current while the output voltage is ramping to a threshold voltage; and
operate the charge pump in a voltage regulation mode in which a second clock signal based on the output voltage is provided to the clock input to regulate the output voltage to a target voltage after the output voltage has ramped up above the threshold voltage.
