Systems and methods for operating a memory include a sensing circuitry connected to a memory cell through an address decoder, a precharge circuitry configured to be connected to the sensing circuitry during a precharge stage and at least partially disconnected from the sensing circuitry during a sensing stage immediately following the precharge stage, and a reference voltage provided to the precharge circuitry, wherein the reference voltage is mirrored to the memory cell by mirroring a current flowing from the precharge circuitry with a current flowing from the sensing circuitry during the precharge stage.
