System, method and program product for well-bias set point adjustment

A method comprising:

• determining that an integrated circuit is to enter into a mode of operation;
• determining if a lower supply voltage relative to a nominal supply voltage of the integrated circuit will be applied during the mode of operation;
• setting a well-bias circuit to apply a first level of well-bias to the charge wells of the integrated circuit if the lower supply voltage will be supplied during the mode of operation;
• and
• setting the well-bias circuit to apply a second level of well-bias to the charge wells of the integrated circuit if the lower supply voltage will not be supplied to the integrated circuit during the mode of operation.

An article of manufacture comprising a machine-readable medium including program logic embedded therein for setting a well-bias point that causes circuitry to perform the steps of:

• determining that an integrated circuit is to enter into a low power mode of operation where the system operates at a supply voltage of a magnitude lower than a nominal supply voltage;
• determining if a lower supply voltage relative to a nominal supply voltage of the integrated circuit will be applied during the low power mode of operation;
• setting a well-bias circuit to apply a first level of well-bias to the charge wells of the integrated circuit if the lower supply voltage will be supplied during the low power mode of operation;
• and
• setting the well-bias circuit to apply a second level of well-bias to the charge wells of the integrated circuit if the lower supply voltage will not be supplied to the integrated circuit during the low power mode of operation.
