Abstract
According to embodiments of the present invention, an automatic trim or calibration for a temperature sensor of a chip or memory device is performed on that chip. An embodiment of the present invention includes a calibration unit that increments trim or calibration values provided to the chip temperature sensor and stored in a calibration register. The calibration unit retrieves status bits from the temperature sensor indicating a measured temperature for each calibration value and compares those bits to a reference or target value associated with a target temperature and stored in a reference register. When the status bits satisfy the comparison, the corresponding calibration value is identified as the proper calibration value for the temperature sensor and is subsequently used by the temperature sensor for temperature measurements.
