1. A circuit for outputting temperature data of a semiconductor memory apparatus, the circuit comprising:

  • a temperature detecting circuit configured to generate a temperature voltage corresponding to a change in temperature and outputs the temperature voltage;

    an A/D converter configured to convert the temperature voltage into a first temperature code and outputs the first temperature code; and

    a temperature data correcting unit configured to output a second temperature code obtained by correcting an error of the first temperature code using a correction code.
