ABSTRACT:
A semiconductor apparatus according to the present invention comprises a current source increasing a current volume in compliance with a rise of a temperature and an oscillation circuit driven by the current of the current source and outputting a clock for refresh control. The semiconductor apparatus, preferably, further comprises a memory device performing the refresh in synchronization with the output clock of the oscillation circuit or the divided clock thereof. The semiconductor apparatus, preferably, further comprises a constant voltage source generating a constant voltage using the current source, an oscillation circuit using the current of the current source, and a memory using the constant voltage generated by the constant voltage source as a reference voltage for a power supply circuit and performing the refresh in synchronization with the output clock of the oscillation circuit or the divided clock thereof.
