    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.

    摘要: An object is to provide a power feeding system and a power feeding method which are more convenient for a power feeding user at the power receiving end, without causing increases in complexity and size of devices. An object is to provide a power feeding system and a power feeding method which also allow a power feeding provider (a company) which feeds power (at the power transmitting end) to supply power without waste. A power feeding device which wirelessly supplies power to a power receiver detects the position and the resonant frequency of the power receiver by receiving a position and resonant frequency detection signal using a plurality of sub-carriers having different frequencies from the power receiver, and controls the frequency of a power signal to be transmitted to the power receiver on the basis of the information. An efficient power feeding service can be offered by transmitting a power signal to the power receiver at an optimum frequency for high power transmission efficiency.

    摘要: An object is to provide a demodulation circuit having a sufficient demodulation ability. Another object is to provide an RFID tag which uses a demodulation circuit having a sufficient demodulation ability. A material which enables a reverse current to be small enough, for example, an oxide semiconductor material, which is a wide bandgap semiconductor, is used in part of a transistor included in a demodulation circuit. By using the semiconductor material which enables a reverse current of a transistor to be small enough, a sufficient demodulation ability can be secured even when an electromagnetic wave having a high amplitude is received.

    摘要: In a semiconductor device performing pipeline processing with the use of a reading portion reading an instruction and an arithmetic portion performing an operation in accordance with the instruction, the instruction held in the reading portion is transmitted from the flip-flop to the memory when branch prediction turns out to be wrong. Note that the arithmetic portion controls transmission and reception of the instruction between the flip-flop and the memory which are included in the reading portion. This enables elimination of redundant operations in the reading portion in the case where an instruction read by the reading portion after the branch prediction turns out to be wrong is a subroutine, or the like. That is, the instruction held in the memory is transmitted back to the flip-flop without rereading of the same instruction by the reading portion, whereby the instruction can be output to the arithmetic portion.

    摘要: The data in a volatile memory may conventionally be lost even in case of a very short time power down or supply voltage drop such as an outage or sag. In view of the foregoing, an object is to extend data retention time even with a volatile memory for high-speed data processing. Data retention time can be extended by backing up the data content stored in the volatile memory in a memory including a capacitor and an oxide semiconductor transistor.
