1. A method for controlling an operating condition of a memory array based on temperature, the method comprising:

  • (a) generating a first temperature-dependent reference voltage comprising a negative temperature coefficient;

    (b) generating a second temperature-dependent reference voltage comprising a positive temperature coefficient;

    (c) comparing the first temperature-dependent reference voltage with the second temperature-dependent reference voltage; and

    (d) controlling an operating condition of a memory array based on a result of the comparison of the first and second temperature-dependent reference voltages.
