Abstract
Techniques and corresponding circuitry for deriving a supply a bias voltage for a memory cell array from a received reference voltage is presented. The circuit includes a voltage determination circuit, which is connected to receive the reference voltage and generate from it the bias voltage, a temperature sensing circuit, and a calibration circuit. The calibration circuit is connected to receive the bias voltage and to receive a temperature indication from the temperature sensing circuit and determine from the bias voltage and temperature indication a compensation factor that is supplied to the voltage determination circuit, which adjusts the bias voltage based upon the compensation factor.
