Abstract:
1. A circuit for compensating a temperature measurement range of a semiconductor memory apparatus, comprising: a counter enable signal generating unit configured to input a temperature pulse having a pulse width proportional to temperature and output the temperature pulse as a counter enable signal in response to a control signal; a counter configured to count an oscillator signal when the counter enable signal is enabled, output a counting signal corresponding to a counting result of the oscillator signal and be reset when the counter enable signal is disabled; and an output controlling unit configured to generate the control signal in response to the counting signal and the temperature pulse and configured to output a temperature information code signal proportional to the counting signal when the control signal is enabled and to output the temperature information code signal at a fixed level corresponding to a maximum value of the counting signal by inverting an output of the counter which is reset when the control signal is disabled.
