1. A method for trimming a sense amplifier, comprising:

  • coupling a first sense amplifier to a selected memory cell and a reference circuit during a read operation;

    decoupling the first sense amplifier from the selected memory cell and the reference circuit during a trim operation of the first sense amplifier;

    coupling the selected memory cell and the reference circuit to a second sense amplifier during the trim operation of the first sense amplifier;

    wherein the trim operation comprises determining a current level to apply to the first sense amplifier to compensate for transistor mismatching.
