  • Patent number: 7126369
    Abstract: A transceiver provides a high-speed transmission signal using shared resources and reduced area. A differential amplifier has its current source/sink connected to a supply terminal. A multiplexing circuit is configured to connect an input of the differential amplifier to an I/O pad so as to output a received input/output signal to internal integrated circuit logic during one mode, or alternatively connect an output of the differential amplifier to the I/O pad so as to output a signal received from the internal integrated circuit logic for input/output during another mode. A level translation operation on the signal may be performed with respect to outputting the signal received from the internal integrated circuit logic.

  • Patent number: 7009861
    Abstract: A Content Addressable Memory (CAM) cell is presented which provides for improved speed and enhanced reliability. The CAM architecture enables maximal conduction of one of the output series pass transistors in the case of a data mismatch during a search operation thereby producing a minimal voltage drop, low impedance path for charging the bootstrap capacitance at the enabled output controlled switch, and causes one of the series pass transistors to conduct for discharging the bootstrap capacitance at the beginning of the precharge period of the bit lines.
