    • The accuracy of reading characteristics or data of pixels or memory cells in a matrix device is increased. An electronic device includes a plurality of drive lines, a sense line intersecting the drive lines, a plurality of element devices provided at intersections thereof, a detecting circuit, a decoder, and a driver. The detecting circuit can detect a first physical quantity of the sense line and transmit a digital signal obtained by digitizing the first physical quantity to the decoder. Each of the element devices can change the first physical quantity of the sense line in accordance with a signal of the corresponding drive line. The driver can transmit coded signals based on a Hadamard matrix to the decoder and the drive lines. The decoder can perform arithmetic processing with use of the coded signals and the digital signal and calculate values based on second physical quantities of the element devices.
    • 增加了矩阵装置中的像素或存储单元的读取特性或数据的精度。 电子设备包括多个驱动线,与驱动线交叉的感测线,在其交叉处设置的多个元件装置,检测电路,解码器和驱动器。 检测电路可以检测感测线的第一物理量,并将通过将第一物理量数字化而获得的数字信号发送到解码器。 每个元件装置可以根据对应的驱动线的信号改变感测线的第一物理量。 驱动器可以将基于Hadamard矩阵的编码信号发送到解码器和驱动线。 解码器可以使用编码信号和数字信号执行算术处理,并且基于元件装置的第二物理量来计算值。
