Abstract: An integrated circuit device with a single via layer, in which the via layer includes selectable via sites and/or jumpers. The selectable via sites and/or placement of jumpers may be used to configure and interconnect components and circuitry between distinct layers of multilayer circuits. In some implementations, selectively enabling via sites by filling via openings and/or using jumpers may implement a data strobe generation circuit with a first via configuration and/or a data buffer circuit with a second configuration.

Abstract: An electronic circuit system includes a main device that generates first and second strobe signals and a clock signal, a first peripheral device that uses the first strobe signal to generate a first output signal in a first lane in response to the clock signal, and a second peripheral device that uses the second strobe signal to generate a second output signal in a second lane in response to the clock signal. The main device determines if the first peripheral device is coupled to the main device through the first lane based on the first output signal. The main device determines if the second peripheral device is coupled to the main device through the second lane based on the second output signal. The main device also has the ability to detect if a peripheral device is faulty and to select a valid configuration of peripheral devices.
