Peak current reduction using dynamic clocking during charge pump recovery period

An apparatus comprising:

• a charge pump operatively coupled with one or more wordlines of a memory array;
• and
• a voltage-controlled oscillator coupled with an output of the charge pump, the voltage-controlled oscillator to provide clock signals to the charge pump depending on a voltage level of the output of the charge pump, wherein the voltage-controlled oscillator is to perform operations comprising:
• detecting that the charge pump has entered a recovery period;
• outputting, to the charge pump during a first time period of the recovery period and responsive to the detecting that the charge pump has entered the recovery period, a first clock signal comprising a lower frequency than output during a time period preceding the recovery period;
• detecting that a voltage level from the charge pump satisfies a trip point criterion;
• and
• outputting, to the charge pump during a second time period of the recovery period, a second clock signal comprising a higher frequency than output during the time period preceding the recovery period.

A method comprising:

• detecting, using control logic operatively coupled with a clock, that a charge pump has entered a recovery period, the charge pump coupled to one or more wordline of a memory array;
• and
• generating, by the control logic, trim bits to trigger frequency stepping within the clock, wherein the frequency stepping comprises:
• outputting, to the charge pump during a first time period of the recovery period, a first clock signal comprising a lower frequency than output during a time period preceding the recovery period;
• and
• outputting, to the charge pump during a second time period of the recovery period, a second clock signal comprising a higher frequency than output during the time period preceding the recovery period.
