Claim:
1. A semiconductor device, comprising: a temperature sensor circuit setting a temperature range upper limit value and a temperature range lower limit value, the temperature sensor circuit provides a first direction output signal and a second direction output signal, the first direction output signal having a logic level transition in response to a temperature of the semiconductor device reaching about the temperature range upper limit value and the second direction output signal having a logic level transition in response to the temperature of the semiconductor device reaching about the temperature range lower limit value; and a single counter circuit coupled to receive the first direction output signal and the second direction output signal and provide a count value, the single counter circuit incrementally changes the count value by an incremental amount in a first direction in response to the first direction output signal and incrementally changes the count value by the incremental amount in a second direction in response to the second direction output signal.
