ABSTRACT:
A clock system produces a high-speed clock signal based on a low-speed clock signal inputted from the outside through the use of a frequency amplifier therein in order to thereby reduce power consumption at a clock buffer. In order to perform the above process, the clock system is composed of an external clock source for producing a clock signal having a frequency of f, a plurality of Rambus DRAMs and a controller, which are synchronized by the clock signal derived from the external clock source. By using the clock system, it is possible to reduce power consumption at the clock buffer and to decrease occurrence of a high frequency noise at a clock pin, and thus, a high qualified system design is also accomplished.
