Abstract:
A system on chip includes an SRAM. The SRAM includes at least one memory cell and a peripheral circuit accessing the at least memory cell. A first power circuit is configured to supply a first driving voltage to the at least one memory cell. A second power circuit is configured to supply a second driving voltage to the peripheral circuit. The SRAM further includes an auto power switch that selects the higher of the first driving voltage and the second driving voltage and supplies the selected voltage to the at least one memory cell.
