ABSTRACT:
An oscillator circuit for a semiconductor device is disclosed which can generate internal clocks having a stable period regardless of variations of a process of transistors and resistors, a power voltage and a temperature, by controlling an oscillator unit by separating a gate voltage and a reference voltage, and which can normally operate chip functions according to the stable internal clocks without suffering from large variations by external factors.
