Patent number: 7816795Abstract: Synchronization between command and address signals commonly coupled to a plurality of memory devices to be operated in parallel and a clock signal coupled to the memory devices is achieved, while suppressing an increase in the clock wiring length. A semiconductor device has a data processing device mounted on a wiring substrate and a plurality of memory devices accessed in parallel by the data processing device. The data processing device outputs the command and address signals as a first frequency from command and address terminals, and outputs a clock signal as a second frequency from a clock terminal. The second frequency is set to multiple times of the first frequency, and an output timing equal to or earlier than a cycle starting phase of the clock signal output from the clock terminal can be selected to the command and address signals output from the command and address terminals.Type: GrantFiled: December 23, 2008Date of Patent: October 19, 2010Assignee: Renensas Electronics CorporationInventors: Toru Hayashi, Motoo Suwa, Kazuo Murakami
