Abstract
The present invention provides a temperature sensitive ring oscillator (TSRO) in an integrated circuit. A temperature measuring device, such as a thermal resistor, is proximate the TSRO, which shares a substantially similar temperature. A memory is employable for storing data that is a function of the output of the TSRO and the temperature measuring device.
