Abstract
A method of reducing leakage current in a memory circuit is disclosed (FIG.A). The method includes connecting a first supply voltage terminal (VDD) to a bulk terminal of a transistor in an active mode of operation. The method further includes detecting a low power mode (SLEEP) of operation of the transistor and disconnecting the first supply voltage terminal from the bulk terminal in response to the step of detecting.
