Abstract:
A static random access memory (SRAM) macro includes a first power supply voltage and a second power supply voltage that is different from the first power supply voltage. A precharge control is connected to the second power supply voltage. The precharge control is coupled to a bit line through a bit line precharge. At least one level shifter receives a level shifter input. The level shifter converts the level shifter input having a voltage level closer to the first power supply voltage than the second power supply voltage to a level shifter output having a voltage level closer to the second power supply voltage than the first power supply voltage. The level shifter output is provided to the precharge control.
