    摘要: A programmable analog device in which data can be held even when supply of a power supply potential is stopped. The programmable circuit includes unit cells connected in parallel or in series, and each of the unit cells includes an analog element. A conduction state of each of the unit cells is changed between an on state and an off state. Each of the unit cells includes, as a switch of the unit cell, a first transistor having a sufficiently low off-state current and a second transistor, a gate electrode of the second transistor being electrically connected to a source or drain electrode of the first transistor. The conduction state of the unit cell is controlled with a potential of the gate electrode of the second transistor, which can be kept even when no power is supplied thanks to the low off-state current of the first transistor.

    摘要: It is an object to prevent miswriting by radio in a relatively easy way in a semiconductor device which is capable of data communication (reception/transmission) through wireless communication, in particular, in an RFID tag provided with an OTP memory or a write-once memory. Alternatively, it is an object to prevent data from being tampered. Further alternatively, it is an object to inhibit access to a memory in a relatively easy way and to inhibit reading of data in a semiconductor device which is capable of data communication (reception/transmission) through wireless communication. In a semiconductor device including a control circuit and an OTP memory, a memory includes at least a sector for preventing additional writing and an information sector. When data for preventing additional writing is written to the sector for preventing additional writing and information is written to the information sector which is electrically connected to the sector for preventing additional writing, additional writing to the information sector to which the information is written is impossible.
