Abstract
A data I/O apparatus for use in a memory device. The data I/O apparatus for use in the memory device performs data transmission using the same polarity when neighbor global I/O lines have opposite polarities to reduce coupling noise generated between global I/O lines acting as data I/O lines of a memory device, performs data recovery, and basically deletes the coupling noise, such that it reduces the failure rate of the memory device.
Claims2
A data Input/Output (I/O) apparatus for use in a memory device, comprising:
- an I/O sense amplifier for outputting a first Global Input Output (GIO) signal and a neighboring GIO signal;
- a transceiver configured to receive the first GIO signal and the neighboring GIO signal;
- and
- a receiver configured to receive the output signal of the transceiver, and
- an output driver configured to receive the output of the receiver for driving,
- wherein the transceiver is configured to convert the polarity of the GIO signal when the polarity of the GIO signal is different from that of a neighboring GIO signal, and the receiver configured to convert the polarity of the GIO signal if polarity of the GIO signal was converted by the transceiver.
