A method and an electronic circuit, the electronic circuit includes: a module that comprises multiple flip-flops and a control signal providing circuit; a power management circuit arranged to provide to the module a supply voltage of a functional level when the module is in a functional mode, and to provide to the module a supply voltage of an idle level when the module is in an idle mode; wherein the control signal providing circuit is arranged to provide to the multiple flip-flops, when the module is in the functional mode, a control signal that facilitates a state change of each of the multiple flip-flops; wherein the control signal providing circuit is arranged to provide to the multiple flip-flops, when the module is in the idle mode, a control signal that prevents a state change of each of the multiple flip-flops; wherein the each of the control signal providing circuit and a plurality of flip-flops of the multiple flip-flops comprises at least one hybrid circuit that comprises a low-threshold transistor that is coupled in parallel to at least one high-threshold transistor; wherein each hybrid circuit is arranged to maintain information or a control signal when provided with the supply voltage of the idle level; and wherein high-threshold transistors of each hybrid circuit are arranged to maintain information or a control signal when provided with a supply voltage of a level that is higher than the idle level. |
