Regulator circuit for independent adjustment of pumps in multiple modes of operation

A method of operating a regulator circuit for a voltage pump, said method comprising:

• applying a first voltage to a resistive circuit to generate a reference voltage;
• determining an operating mode of the circuit;
• and
• applying a plurality of adjustment circuits to the resistive circuit to generate an adjusted reference voltage if the determined operating mode requires the reference voltage to be adjusted.

A method of operating a memory circuit, said method comprising

• generating a pumped voltage;
• applying the pumped voltage to the memory circuit;
• and
• regulating the pumped voltage, said regulating step comprising:
• generating a reference voltage from the pumped voltage,
• determining an operating mode of the circuit, and
• applying one of a plurality of adjustment circuits to a circuit generating the reference voltage to generate an adjusted reference voltage if the determined operating mode requires the reference voltage to be adjusted.
