    • PURPOSE: A self compensation circuit of a semiconductor device is provided to adapt positively to the variation of a manufacturing process, an operation voltage and an operation temperature to stabilize the operation characteristics. CONSTITUTION: The self compensation circuit of the semiconductor device includes an oscillator(201), a counter(202,204) and a decoder(206) and a controller(207). The oscillator generates frequency pulses(FREQ1-FREQ13) with response to a characteristic variation.
