CIRCUIT AND METHOD ABOUT SLEEP STATE LEAKAGE CURRENT REDUCTION

摘要

PROBLEM TO BE SOLVED: To reduce leakage current in a sleep state.SOLUTION: A circuit 100 for reducing leakage current in a sleep state includes a latch, a flip-flop, a comparator, a multiplexer, or a hardware unit 102 selected from one among adders. The hardware unit 102 includes a first node 110, and further includes a sleepable combination logic 104 in which the value of the first node is stored during a sleep state, and the hardware unit is connected to the first node.
