    • A semiconductor device is provided to prevent data transmitted from the semiconductor device to a reader/writer from being wrongly recognized as data transmitted from the reader/writer to the semiconductor device to improve the reliability of the semiconductor device. A semiconductor device(101) includes an antenna circuit(102), a transmission circuit(103), a receiving circuit(104) and an operation processing circuit(105). The antenna circuit transmits and receives an RF signal, rectifies the RF signal, outputs the rectified RF signal to the transmission circuit, and modulates the RF signal according to a modulation signal inputted from the transmission circuit. The transmission circuit generates the modulation signal from transmission data output from the operation processing circuit, outputs the modulation signal to the antenna circuit and outputs a signal indicating whether the RF signal is transmitted from the antenna circuit to a reader/writer. The receiving circuit generates a demodulation signal from the rectified signal inputted from the antenna circuit and the signal indicating whether the RF signal is transmitted and outputs the demodulation signal to the operation processing circuit. The operation processing circuit performs an operation using the demodulation signal and outputs the transmission data to the transmission circuit.
    • 提供一种半导体器件,用于防止从半导体器件发送到读取器/写入器的数据被错误地识别为从读取器/写入器传输到半导体器件的数据,以提高半导体器件的可靠性。 半导体器件(101)包括天线电路(102),发送电路(103),接收电路(104)和运算处理电路(105)。 天线电路发送和接收RF信号,整流RF信号,将经整流的RF信号输出到发送电路,并根据从发送电路输入的调制信号对RF信号进行调制。 发送电路从运算处理电路输出的发送数据生成调制信号,将调制信号输出到天线电路,并输出表示RF信号是否从天线电路发送到读写器的信号。 接收电路根据从天线电路输入的整流信号和指示RF信号是否发送的信号产生解调信号,并将解调信号输出到运算处理电路。 操作处理电路使用解调信号进行操作,并将发送数据输出到发送电路。
