Input/output interfacing circuit, input/output interface, and semiconductor device having input/out interfacing circuit |
摘要 |
The current generating unit in the transmitter generates output currents in accordance with a plurality of logic values. The reference current generating unit in the receiver generates a plurality of reference currents. The current comparing units in the receiver respectively compares reference currents with output current from the transmitter and restores the logic values. That is, the current is varied in correspondence with the logic values that are transmitted from the transmitter to the receiver, wherein the logic values are restored in the receiver according to a difference in the current value. Forming a plurality of current comparing units in the receiver makes it possible to easily compare the values of the output current from the transmitter and a plurality of reference currents. Therefore, the number of multi-valued bits can be easily increased so as to construct a high bit-rate multi-valued input/output interface.
