Circuit and method of outputting temperature data of semiconductor memory apparatus

摘要

A circuit for outputting temperature data of a semiconductor memory apparatus includes a temperature detecting circuit that generates a temperature voltage corresponding to a change in temperature and outputs the temperature voltage, an A/D converter that converts the temperature voltage into a first temperature code and outputs it, and a temperature data correcting unit that outputs a second temperature code obtained by correcting an error of the first temperature code using a correction code.
