ABSTRACT:
An integrated circuit includes a supply voltage controller operable to receive a plurality of control signals and at least one circuit supply voltage and to output at least one variable supply voltage to at least one supply terminal of the integrated circuit The controller is operable to switch the variable supply voltage to a first voltage level when the control signals define a first operation and to a second voltage level different from the first voltage level when the control signals define a second operation. The controller is also operable to float the variable supply voltage to a third voltage level different from the first voltage level when the control signals define a third operation.
