摘要： An object is to provide a programmable logic device having logic blocks connected to each other by a programmable switch, where the programmable switch is characterized by an oxide semiconductor transistor incorporated therein. The extremely low off-state current of the oxide semiconductor transistor provides a function as a non-volatile memory due to its high ability to hold a potential of a gate electrode of a transistor which is connected to the oxide semiconductor transistor. The ability of the oxide semiconductor transistor to function as a non-volatile memory allows the configuration data for controlling the connection of the logic blocks to be maintained even in the absence of a power supply potential. Hence, the rewriting process of the configuration data at starting of the device can be omitted, which contributes to the reduction in power consumption of the device.
摘要翻译：目的是提供一种具有通过可编程开关彼此连接的逻辑块的可编程逻辑器件，其中可编程开关的特征在于结合在其中的氧化物半导体晶体管。氧化物半导体晶体管的非常低的截止电流由于其保持与氧化物半导体晶体管连接的晶体管的栅极的电位的高能力而提供作为非易失性存储器的功能。氧化物半导体晶体管用作非易失性存储器的能力允许用于控制逻辑块的连接的配置数据即使在没有电源电位的情况下也被维持。因此，可以省略在设备启动时的配置数据的重写处理，这有助于降低设备的功耗。

摘要： In a wireless tag with which a wireless communication system whose electric power of a carrier wave from a R/W is high, an overvoltage protection circuit is provided to prevent from generating excessive electric power in the wireless tag when the wireless tag receives excessive electric power. However, as noise is generated by operation of the overvoltage protection circuit, an error of reception occurs in receiving a signal whose modulation factor is small. To solve the problem, the maximum value of generated voltage in the wireless tag is held in a memory circuit after the overvoltage protection circuit operates, then the overvoltage protection circuit is controlled in accordance with the maximum value of generated voltage. The voltages at which the overvoltage protection circuit starts and stops operating are different from each other, and hysteresis occurs between the timing when the overvoltage protection circuit starts and stops operating.

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.
摘要翻译：在利用读取指令的读取部分执行流水线处理的半导体器件和执行根据该指令的操作的算术部分中，当分支预测时，保持在读取部分中的指令从触发器发送到存储器原来是错的。注意，算术部分控制包括在读取部分中的触发器和存储器之间的指令的发送和接收。在分支预测结果为错误的读取部读出的指示是子程序等的情况下，能够消除读取部中的冗余动作。也就是说，保持在存储器中的指令被发送回到触发器，而不用读取部分重新读取相同的指令，从而可以将该指令输出到算术部分。
