ABSTRACT:
A signal transmission system is provided which can accurately recognize data even if two signals are superimposed on each other on the same signal line. The potential of a read signal indicating read data is designated (a), and the potential of a write signal indicating write data is designated (b). Consequently, the potential of a signal where the read signal and the write signal are superimposed (that is, the superimposed signal) is designated as (c). As a result, the value of write data can be accurately recognized from the superimposed signal, using a reference potential of 1.75V. On the other hand, the value of read data can be accurately recognized from the superimposed signal, using the reference potential of 2.25V when the write data is “H”, or 1.25V when the write data is “L”.
