Patent ID: 8087823

Claim:
An apparatus comprising: a structure, said structure generating heat as power is supplied to said structure; a heat dissipating feature attached to said structure; an internal temperature measurement device internal to said structure, a threshold voltage of said internal temperature measurement device changing as a temperature of said temperature measurement device changes; and storage internal to said structure storing a linear relationship between temperature and threshold voltage, said linear relationship being established by: heating said structure to a first temperature and recording a first threshold voltage of said internal temperature measurement device at said first temperature, heating said structure to a second temperature, different than said first temperature, and recording a second threshold voltage of said internal temperature measurement device at said second temperature, and calculating said linear relationship based on said first temperature, said first threshold voltage, said second temperature, and said second threshold voltage, and temperatures of said structure being determined based only upon said linear relationship and threshold voltages measured from said internal temperature measurement devices.
