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.

摘要： Provided is a startup circuit which allows a reference voltage generating circuit to start up and reach a stable equilibrium state in an extremely short period. The startup circuit is configured to hold voltage which is substantially the same as internal voltage of the reference voltage generating circuit in the stable equilibrium state even when power is not supplied to the startup circuit. The voltage is output from the startup circuit to the reference voltage generation circuit when the reference voltage generating circuit is started.
