Abstract
A semiconductor integrated circuit device including input and output registers, a data-processing circuit block disposed between the registers, a first PLL circuit for supplying a first output clock signal to the input register in response to an input clock signal, and a second PLL circuit for supplying a second output clock signal to the output register in response to the input clock signal. The input register transfers a data signal stored therein to the output register in response to the first output clock signal. The output register stores the data signal and transfers it to another device in response to the second output clock signal. The first and second PLL circuits supply the first and second output clock signals to the input and output registers with keeping the phase differences constant, respectively. The data signal stored in the input register can be correctly transferred to the output register, and the data signal stored in the output register can be correctly transferred to an input register of another semiconductor integrated circuit device even if the clock skew arises.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
