INTEGRATED CIRCUIT HAVING DATA RETENTION CIRCUITRY WITH LOW LEAKAGE AND METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a system and method for data retention circuitry with low leakage.SOLUTION: An integrated circuit comprises: a first circuit; and a sleep transistor circuit. The first circuit receives input signals and processes the input signals. The first circuit also retains data in a sleep state that has low leakage. The sleep transistor circuit is coupled to the first circuit and receives a sleep signal that has a negative voltage. The sleep circuit reduces power consumption of the first circuit in the sleep state to have low leakage on the basis of the sleep signal while retaining the data in the first circuit.
