Summary:An apparatus and method are provided for limiting a drop of a supply voltage in an SRAM device to retain the state of the memory during an IDLE state. The apparatus may include a memory array, a sleep device, and a clamping circuit. The clamping circuit may be configured to activate the sleep device when a voltage drop across the memory array falls below a preset voltage and the memory array is in an IDLE state.
