Publication number: 20080309383Abstract: A semiconductor integrated circuit includes a memory circuit, an oscillator circuit which generates an internal clock signal, based on control information held in the memory circuit, and a logic circuit which generates control information that causes the frequency of the internal clock signal to coincide with the frequency of an external clock signal. The internal clock signal is used for a synchronous operation of an internal circuit. Even if an error (undesired variation) occurs in the oscillation characteristic of the oscillator circuit due to process variations, it is possible to cause an internal clock signal frequency to coincide with an external clock signal frequency corresponding to a target frequency without the need for external attachment of a crystal oscillator and the input of an external clock signal.Type: ApplicationFiled: April 21, 2008Publication date: December 18, 2008Inventors: Naoki Yada, Yasuyuki Saito, Yasushi Shibatsuka, Katsunori Koike, Mitsuhiko Okutsu
