| 14. A Non-Volatile Memory apparatus comprising: a control circuit for controlling operation of a charge pump (CP) pipe having
an input receiving a supply voltage (Vsupply), a number of stages, and an output (Vout, Iout), said control circuit including
means for measuring current consumption (Icp_in) in the charge pump pipe, and means for measuring a second current (I.sub.2) coming into a driver for at least one of the one or more stages of the charge pump, and
means for decreasing or increasing the current consumption (Icp_in) by adjusting one or more of:
a. a supply voltage (Vsupply);
b. a stage's voltage (V.phi.);
c. the stage's frequency and/or duty-cycle;
d. the number (N) of stages; and
e. adjusting a load connected to the output of the charge pump pipe.
