    • An object is to provide an image processing circuit adaptable to displays having a variety of pixel numbers. The image processing circuit includes a data adjustment circuit, a first line memory and a second line memory capable of storing K pieces of data, an output timing control circuit, and an arithmetic circuit. To the data adjustment circuit, (X×Y) pieces of pixel data are input. Y pieces of pixel data are transmitted to the first line memory. When Y is less than K, (K−Y) pieces of dummy data are added to fill the first line memory. Then, the K pieces of data are output from the first line memory to the second line memory and a new set of K data is input to the first line memory. The arithmetic circuit stores the data input from the line memories and performs filtering.

    • In a case where an ASK method is used for a communication method between a semiconductor device and a reader/writer, the amplitude of a radio signal is changed by data transmitted from the semiconductor device to the reader/writer when data is not transmitted from the reader/writer to the semiconductor device. Therefore, in some cases, the semiconductor device mistakes data transmitted from the semiconductor device itself for data transmitted from the reader/writer to the semiconductor device. The semiconductor device includes an antenna circuit, a transmission circuit, a reception circuit, and an arithmetic processing circuit. The antenna circuit transmits and receives a radio signal. The transmission circuit outputs to the reception circuit a signal showing whether or not the antenna circuit is transmitting the radio signal.
    • 在使用ASK方式进行半导体装置与读取器/写入器之间的通信方式的情况下,通过从半导体装置发送到读取器/写入器的数据,无线信号的振幅由数据不从 读取器/写入器到半导体器件。 因此,在某些情况下,半导体器件将从半导体器件本身发送的数据错误地从读取器/写入器发送到半导体器件的数据。 半导体器件包括天线电路,发送电路,接收电路和运算处理电路。 天线电路发送和接收无线电信号。 发送电路向接收电路输出表示天线电路是否正在发送无线信号的信号。

    • A memory device according to the invention can be operated with a single potential, by which the use of a voltage converter can be excluded, leading to the reduction of power consumption. Such an operation can be achieved by utilizing capacitive coupling of a capacitor connected to a gate of a transistor for data writing. That is, the capacitive coupling is induced by inputting a signal, which is supplied by a delay circuit configured to delay a write signal having a potential equal to the power supply potential, to the capacitor. Increase in the potential of the gate by the capacitive coupling allows the transistor to be turned on in association with the power supply potential applied to the gate from a power supply. Data is written by inputting a signal having a potential equal to the power supply potential or a grounded potential to a node through the transistor.
    • 根据本发明的存储器件可以以单个电位工作,通过该电位可以排除使用电压转换器,导致功耗的降低。 这种操作可以通过利用连接到晶体管的栅极的电容器进行数据写入的电容耦合来实现。 也就是说,通过输入由延迟电路提供的信号来感应电容耦合,该延迟电路被配置为将具有等于电源电位的电位的写入信号延迟到电容器。 通过电容耦合增加栅极的电位使晶体管与从电源施加到栅极的电源电位相关联地导通。 通过晶体管将具有等于电源电位的电位或接地电位的信号输入到节点来写入数据。
