Integrated circuits, systems, and methods for reducing leakage currents in a retention mode

摘要

An integrated circuit includes at least one memory array for storing data. A first switch is coupled with the memory array. A first power line is coupled with the first switch. The first power line is operable to supply a first power voltage. A second switch is coupled with the memory array. A second power line is coupled with the second switch. The second power line is operable to supply a second power voltage for retaining the data during a retention mode. A third power line is coupled with the memory array. The third power line is capable of providing a third power voltage.
