Patent ID: 7161847

Claim:
A data Input/Output (I/O) apparatus for use in a memory device, comprising: a transceiver for receiving a plurality of Global Input Output (GIO) signals from an I/O sense amplifiers contained in each bank of the memory device, comparing the received GIO signals with their neighbor GIO signals thereby generating at least one control signal, converting the GIO signals to have the same polarities as those of the neighbor GIO signals in response to the at least one control signal, and outputting the GIO signals including the converted GIO signals along with the at least one control signal; and a receiver for receiving the GIO signals and the at least one control signal from the transceiver, recovering the polarities of the converted GIO signals in response to the at least one control signal, and transmitting the GIO signals including the polarity-recovered GIO signals to an output driver.
