An apparatus and a method for adding capacitance while conserving circuit board surface area. An apparatus for adding capacitance while conserving circuit board surface area includes a flex capacitor circuit with an upper surface and a lower surface and a plurality of conductive layers and an integrated-circuit (IC) device mounted on to the upper surface of the flex capacitor circuit and electrically connected to the flex capacitor circuit. The flex capacitor circuit is configured to provide bypass capacitance and, therefore, adds capacitance to the IC device when the IC device is mounted on the flex capacitor circuit.

Flex circuit apparatus and method for adding capacitance while conserving circuit board surface area

A memory module having a DRAM device configured to generate a low DQS state on a DQS line, and a buffer coupled to the DRAM device, the buffer having a plurality of drivers, wherein the buffer is configured to detect the low DQS state by comparing the low DQS state to a low voltage level of one of the plurality of drivers.

Buffered memory device

An improved method and apparatus for altering the effective electrical length of trace on a circuit board. In the present invention small tabs of etch are routed perpendicular to the trace in the unused areas between adjacent traces. In an embodiment of the invention, a method of tuning the delay characteristics of a transmission line is implemented by inserting compensation tabs into the unused area between the segments of adjacent straight traces or a serpentine run. Utilizing the method and apparatus of the present invention, it is possible to achieve significantly greater electrical length for an electrical trace without introducing coupling problems or utilizing large amounts of space on a circuit board.
