Abstract
A semiconductor device that can transmit and receive data without contact is popular partly as some railway passes, electronic money cards, and the like; however, it has been a prime task to provide an inexpensive semiconductor device for further popularization. In view of the above current conditions, a semiconductor device of the present invention includes a memory with a simple structure for providing an inexpensive semiconductor device and a manufacturing method thereof. A memory element included in the memory includes a layer containing an organic compound, and a source electrode or a drain electrode of a TFT provided in the memory element portion is used as a conductive layer which forms a bit line of the memory element.
