A programmable interconnect for programmably connecting transmission lines which are part of a configurable logic array is combined with a buffer at locations within the logic array where a signal will travel from a low capacitance line to a higher capacitance line. Use of a buffer in this arrangement allows for programmable interconnects controlling the configuration of the logic array to be smaller; consuming less power and providing for faster rise and fall of an output signal even when propagating through a long series of programmable interconnects. Several arrangements for programmably controlling the interconnect are taught. Also taught is a means of achieving a very wide AND gate without the need for cascading smaller devices.
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.
