Boosted supply voltage generator and method therefore

A circuit comprising:

• a node that includes capacitance configured to store charge corresponding to a boosted supply voltage;
• a voltage generator coupled to the node, the voltage generator configured to provide charge to the node such that, at a target charge level, the boosted supply voltage is greater than a logic supply voltage for a device on which the circuit is included;
• state storage circuitry;
• control circuitry coupled to the voltage generator and the state storage circuitry, the control circuitry configured to:
• deactivate the voltage generator;
• store state information corresponding to deactivation of the voltage generator in the state storage circuitry;
• and
• reactivate the voltage generator using the state information stored in the state storage circuitry.

An apparatus, comprising:

• a node;
• a clock provider that provides a clock, wherein the clock is a signal that has defined phases;
• a charge pump coupled to the node and the clock provider, the charge pump including an internal node, wherein:
• during a first phase of the clock, the internal node of the charge pump is charged;
• and
• during a second phase of the clock, charge on the internal node of the charge pump is discharged to the node to generate a supply voltage at the node that is greater than a logic supply voltage provided to the apparatus;
• state storage circuitry;
• and
• control circuitry coupled to the charge pump, the clock provider, and the state storage circuitry, wherein the control circuitry is configured to:
• deactivate the charge pump by stopping provision of the clock to the charge pump;
• store state information corresponding to deactivation of the voltage generator in the state storage circuitry;
• and
• reactivate the charge pump using the state information stored in the state storage circuitry.
