Abstract

Leakage current control devices include a circuit having one or more functions in a data path where the functions are executed in a sequence. Each of the functions has power reduction logic to energize each respective function. A leakage control circuit interacts with the power reduction logic, so that the functions are energized or deenergized in a control sequence such that the functions where the data is resident are energized and at least one of the other functions is not energized.
