SEMICONDUCTOR APPARATUS
First Claim
1. A semiconductor apparatus comprising:
- a control block configured to generate a first control signal, a second control signal, and a heating enable signal in response to an enable signal and a heating control signal;
a temperature measurement block configured to generate a temperature code corresponding to temperature in response to the first and second control signals;
a heater configured to generate heat while the heating enable signal is being enabled;
a code latch block configured to store the temperature code in response to the first and second control signals, and output a first code and a second code;
a control code generation circuit configured to generate a signal by performing an operation on the first and second codes, and generate a control code by comparing the signal with a preset code; and
a reference voltage generation circuit configured to change a voltage level of a reference voltage in response to the control code.
