Abstract: A semiconductor device is provided. The semiconductor device includes a semiconductor substrate, a first deep well region, at least two second well regions, at least one isolation structure and an implantation region. The first deep well region is disposed in the semiconductor substrate, wherein the first deep well region has a first conductivity type. The second well regions are disposed on the first deep well region, wherein the second well regions have a second conductivity type. The isolation structure covers a portion of the first deep well region and surrounds at least a portion of the second well regions. The implantation region is located under a top surface of the semiconductor substrate, wherein the implantation region has a discontinuous portion, and the discontinuous portion partially overlaps the first deep well region.

Abstract: A bus architecture and a data transmission method thereof are applicable to a signal transmission environment between functioning components of an information system, so as to transmit data, addresses and/or control signals between any two of the functioning components of the information system in a serial transmission manner via at least one wire. During the data transmission method, the bus architecture can convert a parallel signal to a serial signal and/or convert a serial signal to a parallel signal, and the sequence of the two conversions being performed or the proceeding of only one or both of the conversions depends on practical requirements.
