Abstract
A combined global data line load and multiplexer comprises a decoder, a bias generator circuit, at least one output signal line pair, and a plurality of switching portions. The decoder provides a plurality of select signals in response to a portion of an address, each select signal provided at either a logic high voltage or at a logic low voltage. For example, a X4 memory internally organized X8 uses one extra address bit to select between two sets of four global data line pairs to provide as outputs. The bias generator circuit provides a bias signal at a voltage between the logic high and the logic low voltages. The output signal lines are each coupled through a respective resistor to a power supply voltage terminal. Each switching portion provides substantially a differential current between corresponding global data lines to corresponding output signal lines in response to the bias voltage exceeding a voltage of a corresponding select signal.
