Abstract
A semiconductor device is used as one of a plurality of slaves connected in multiple stages to a master and transmits a frame signal output from the master sequentially from a preceding stage to a subsequent stage. The frame signal includes synchronization bits and a message string (for example, command bits, address bits, and guard bits) following the synchronization bits. The semiconductor device includes a logic circuit configured to sample the frame signal at a baud rate corresponding to the synchronization bits and an output stage configured to through-outputs the synchronization bits before sampling without passing them through the logic circuit.
