A semiconductor device for storing data includes a memory cell. The memory cell comprises a plurality of transistors. A trimmable sense amplifier is electrically connected to the memory cell. The trimmable sense amplifier is configured to provide variable current to said memory cell. A charge pump is also electrically connected to the memory cell. The charge pump includes a plurality of diodes disposed in series with one another. The charge pump includes an input for receiving an input voltage and an output for providing an output voltage greater than the input voltage to the memory cell.
