  • Patent number: 9240248
    Abstract: An integrated circuit device. The device includes an address input(s) configured to receive address information from an address stream from an address command bus coupled to a host controller and an address output(s) configured to drive address information, and is coupled to a plurality of memory (DRAM) devices provided on a DIMM. The device has an address match table comprising a non-volatile memory device configured to store at least a revised address corresponding to a spare memory location and a bad address of at least one of the plurality of memory (DRAM) devices. The device has a control module configured to process and determine whether each address matches with a stored address in the address match table to identify the bad address and configured to replace the bad address with the revised address of the spare memory location.

  • Patent number: 7102444
    Abstract: A method and apparatus for an amplifier, such as a radio frequency amplifier embodiment as an integrated circuit is disclosed. Embodiments provide for operating with good energy efficiency at multiple power levels. Resonant components act to provide consistent operating parameters over the wide range of power levels used. A compensating impedance is switched into or out of circuit in high power mode to improve the match that would pertain without the compensation. Improved compensation and linearity may be provided using features disclosed. The invention may operate in the microwave region or at other RFs.
